The value of other Zeroes are -1/2,2

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial (No division operation by a variable)

Algebraic expressions known as polynomials can have exponents that are multiplied, divided, or added. Polynomials come in various varieties. Monomial, binomial, and trinomial, respectively. A monomial is a polynomial with only one term. A polynomial having two dissimilar terms is called a binomial.

Given ,

p(x)=2x ³ +3x² −11x−6

Since x=−3 is a zero of p(x)

So, by factor theorem x+3 is a factor of p(x)

Now, if we divide 2x³+3x²−11x−6 by x+3, quotient is 2x² −3x−2 and remainder is 0.

Therefore,

2x³+3x² −11x=(x+3)(2x² −3x−2)

=(x+3)(2x+1)(x−2)

for other zeroes of p(x)

2x+1=0,x−2=0

Hence the other zeroes are − 1/2,2

The complete question is : Find all the other zeros of the polynomial p(x)=2x³ +3x ² −11x−6 if one of its zero is −3.

In slope intercept form, Equation 14x-20y=-13 can be written as 13 + 4y/20 = y.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation. The slope, m, is a measure of how steep a line is. The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

Given,

A hole in a graph appears as a break in the graph line, while a vertical asymptote appears as a line segment that the graph approaches but never crosses.

A hole in a graph appears as a break in the graph line; it's the point where the graph does not exist. Typically, the x-value of this point is the x-coordinate of the hole. To find out if there is a hole, you need to see if the graph is continuous and check to see if there is a break in the graph line.A vertical asymptote appears as a line segment that the graph approaches but never crosses. This occurs when the function value approaches positive or negative infinity.

Step-by-step explanation:

The square root of 1 is called 1.

In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4. The square root of 9 is 3, because 3 x 3 = 9.

The square root of 1 is 1, because 1 x 1 = 1. Therefore, the square root of 1 is simply called 1.

The value of x in the equation 5/3x + 1/3x = 13⅓ + 8/3x is calculated as: x = -20.

To solve an equation is to find the value of the variable by isolating it in such a way that it is moved to one side of the equation.

Given the equation, 5/3x + 1/3x = 13⅓ + 8/3x, to solve this equation, we need to find the value of x by isolating the variable x to one side.

Follow the steps below:

5/3x + 1/3x = 40/3 + 8/3x

2x = 40/3 + 8/3x

Substract both sides by 8/3x:

2x - 8/3x = 40/3 + 8/3x - 8/3x

-2/3x = 40/3

Multiply both sides by -3/2:

-2/3x × -3/2 = 40/3 × -3/2

x = -120/6

x = -20

The standard form of linear equation in two variables is Ax + By = C.

The standard form of linear equation in two variables is Ax + By = C, where A, B and C are constants and A and B are not both zero. This equation can be used to represent a line on a graph, which can be found by plotting any two points that satisfy the equation.

To calculate the equation of a line in standard form, first identify two points on the line. For example, point (x1, y1) and point (x2, y2). Then, calculate the slope of the line using the formula m = (y2 - y1) / (x2 - x1). The slope determines the constants A and B for the equation. A = m and B = -1. Finally, calculate the constant C by substituting one of the two points into the equation. C = Ax1 + By1.

The number that is 10 more than 40 is 50, using addition.

Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division.The addition of two whole numbers results in the total amount or sum of those values combined. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" (that is, "3 plus 2 is equal to 5").

Besides counting items, addition can also be defined and executed without referring to concrete objects, using abstractions called numbers instead, such as integers, real numbers and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can also be performed on abstract objects such as vectors, matrices, subspaces and subgroups.

To identify whether a mathematical expression represents a "greater than" or "less than" relationship, you can use the following symbols:

Greater than: >

Less than: <

For example, the expression "3 > 2" represents a "greater than" relationship because it means that 3 is greater than 2. Similarly, the expression "5 < 7" represents a "less than" relationship because it means that 5 is less than 7.

You can also use the symbols "greater than or equal to" and "less than or equal to" by using the following symbols:

Greater than or equal to: >=

Less than or equal to: <=

For example, the expression "3 >= 2" represents a "greater than or equal to" relationship because it means that 3 is greater than or equal to 2. Similarly, the expression "5 <= 7" represents a "less than or equal to" relationship because it means that 5 is less than or equal to 7.

A non-homogeneous system of equations is a system in which the vector of constants on the right-hand side of the equal sign is non-zero.

Given:-General solution for the equation: [tex]y^{"} - y^{'} = t[/tex], [tex]y_{p} (t) = - t[/tex]

The nature of roots of the given quadratic equation is "real and unequal".

Nature of Roots:

Root type simply means the category to which the root belongs. Roots can be imaginary, real, unequal, or equal. If the discriminant is negative, the root is imaginary.

Depending on the value of the discriminant, we discuss the following cases for the nature of the root:

Case 1: D = 0

If the discriminant is zero (b2 – 4ac = 0), a, b, and c are real, and a≠0, the root of the quadratic equation is ax2 + bx + c = 0 is Real and equal. In this case the root is x = -b/2a. A graph of the equation is tangent to the x-axis at a point.

Case 2: D > 0

If the discriminant is greater than zero (b2 – 4ac > 0), then a, b, and c are real and a≠0, then the root of the quadratic equation ax2 + bx + c = 0 is real and not equal. The equation graph touches the x-axis at two different points.

Case 3: D < 0

If the discriminant is less than zero (b2 – 4ac < 0), a, b, and c are real, and a≠0, then the root of the quadratic equation ax2 + bx + c = 0 is Imaginary and not equal. Roots exist in conjugate pairs. The equation graph does not touch the x-axis.

Case 4: Perfect Square with D > 0

If D > 0 and Perfect Square, the roots of the quadratic equation are real, unequal, and rational.

Case 5: D > 0 and Not Perfect Square

If D > 0 and not perfect square, the roots of the quadratic equation are real, unequal, and irrational.

According to the Question:

The given quadratic equation:

2x²-4x-3 = 0

Here, a = 2, b = - 4 and c = -3

To Find: the nature of roots of the given quadratic equation.

∴ Discriminant, D = b²-4ac

= (-4)² - 4×2×(-3)

= 16 -8(-3)
