# AP SSC Class 10 Maths Chapter 3 Polynomials

The AP SSC Class 10 Maths Chapter 3 Polynomials discusses polynomials and its various properties. Here, in the article, we have provided a brief explanation of polynomials and methodical solutions to the chapter questions.

## What is a Polynomial?

A polynomial is an algebraic expression constructed using constants and variables. Coefficients can be raised to various powers of non-negative integer exponents. A few examples of polynomials are $3x^{2}+5x+6$, $x^{3}$ and $2x+5$

### Degree of a Polynomial

If p(x) is a polynomial in x, the highest power of x in p(x) is known as the degree of the polynomial p(x).

• A polynomial of degree 1 is known as a linear polynomial. Example, $4x+6$
• A polynomial of degree 2 is known as a quadratic polynomial. Example, $x^{2}+3x+5$
• A polynomial of degree 3 is known as a cubic polynomial. Example, $a^{3}+a^{2}+a+6$

If p(x) is a polynomial in x, and if a is a real number, then the value obtained by replacing x by a in p(x), is called the value of p(x) at x = a, and is denoted by p(a). The value of x that makes the polynomial equal to 0 is known as the zero of a polynomial.

## Class 10 Maths Chapter 3 Polynomials Questions

1. If $p(x)=5x^{7}-4x^{6}+8x-6$, find the
• Coefficient of $x^7$
• Degree of p(x)
• Constant term

Solution:

1. The coefficient of$x^7$ is 5
2. The degree of p(x) is 7
3. The constant term of p(x) is -6
1. If $p(t)=t^{3}-1$, find the values of p(1), p(–1), p(0), p(2), p(–2).
2. Solution:

1. p(1) = $p(t)=1^{3}-1=0$
2. p(–1) = $p(t)=(-1)^{3}-1=-2$
3. p(0) = $p(t)=0^{3}-1=-1$
4. p(2)=$p(t)=2^{3}-1=7$
5. p(–2) =$p(t)=(-2)^{3}-1=-9$
