# How do you find a and b of a polynomial?

## How do you find a and b of a polynomial?

So, put the zeroes of the polynomial in the given polynomial and form two-equation from it and solve two equations in two variable methods to find the value of a and b. Now substitute the value of a in any one of the equations and calculate the value of b.

## What is A and B in a polynomial function?

In the standard formula for degree 1, a represents the slope of a line, the constant b represents the y-intercept of a line. E.g., y = 2x+3(see Figure 2) here a = 2 and b = 3. Figure 2: Graph of Linear Polynomial Functions.

What is converse of factor theorem?

According to factor theorem, if f(x) is a polynomial of degree n ≥ 1 and ‘a’ is any real number, then, (x-a) is a factor of f(x), if f(a)=0. Also, we can say, if (x-a) is a factor of polynomial f(x), then f(a) = 0. This proves the converse of the theorem.

What is factor theorem?

In mathematics, factor theorem is used when factoring the polynomials completely. It is a theorem that links factors and zeros of the polynomial. According to factor theorem, if f(x) is a polynomial of degree n ≥ 1 and ‘a’ is any real number, then, (x-a) is a factor of f(x), if f(a)=0.

### What is the a value in a polynomial?

The value of the polynomial at a point is defined as the value obtained at a specific point for the given function. For example, let the polynomial function be P(x)= x+1.

### What is a factor of a polynomial function?

A factor is one of the linear expressions of a single-variable polynomial. A polynomial can have several factors, such as the factors… (x – 1) and (x + 3). Zeros. When polynomials are graphed, many of them intersect the x-axis.

How do you Factorise using factor theorem?

Factorization Of Polynomials Using Factor Theorem

1. Obtain the polynomial p(x).
2. Obtain the constant term in p(x) and find its all possible factors.
3. Take one of the factors, say a and replace x by it in the given polynomial.
4. Obtain the factors equal in no. to the degree of polynomial.
5. Write p(x) = k (x–a) (x–b) (x–c) …..

Is 51 a polynomial?

What is factor theorem Class 11?

It is a theorem that links factors and zeros of the polynomial. According to factor theorem, if f(x) is a polynomial of degree n ≥ 1 and ‘a’ is any real number, then, (x-a) is a factor of f(x), if f(a)=0. Also, we can say, if (x-a) is a factor of polynomial f(x), then f(a) = 0.

What is the factor theorem?

Hence, (x – c) is a factor of the polynomial f (x). Hence, the Factor Theorem is a special case of Remainder Theorem, which states that a polynomial f (x) has a factor x – a, if and only if, a is a root i.e., f (a) = 0. How to use the Factor Theorem? Let’s see a few examples below to learn how to use the Factor Theorem.

### What is factor theorem class 9 Maths polynomial?

Factor theorem class 9 maths polynomial enables the children to get a knowledge of finding the roots of quadratic expressions and the polynomial equations, which is used for solving complex problems in your higher studies. Consider the polynomial function f (x)= x 2 +2x -15 The values of x for which f (x)=0 are called the roots of the function.

### What does the factor theorem remove from a polynomial?

The factor theorem removes all the known zeros from a given polynomial equation and leaves all the unknown zeros. The resultant polynomial has a lower degree in which the zeros can be easily found out.

How do you prove the converse of the factor theorem?

Also, we can say, if (x-a) is a factor of polynomial f (x), then f (a) = 0. This proves the converse of the theorem. Let us see the proof of this theorem along with examples. What is a Factor Theorem?
