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. Refer to the below given AP SSC 1oth Class Maths Chapter 3 Polynomials Notes and Solutions and learn how to give step-by-step correct solutions for the concepts taught under the subject in class.

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

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,
  \(\begin{array}{l}4x+6\end{array} \)
• A polynomial of degree 2 is known as a quadratic polynomial. Example,
  \(\begin{array}{l}x^{2}+3x+5\end{array} \)
• A polynomial of degree 3 is known as a cubic polynomial. Example,
  \(\begin{array}{l}a^{3}+a^{2}+a+6\end{array} \)

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.
