Important Topics in Class 10 Maths Chapter 2 Polynomials

Algebraic Expressions are expressions formed of variables and constants along with the mathematical operators.

An example of an algebraic expression: 3x²y + 4xy + 5x + 6

A polynomial is an algebraic expression that has an exponent on any variable as a whole number.

For example: x²– 5x + 11

Degree of Polynomial is the highest power of a monomial present in a polynomial expression. The highest exponential power is known as the degree of a polynomial.

For example: The degree of the polynomial x³+ 2x² + 3x + 2 is 3, as the highest power of x in the given expression is 3.

Polynomials can be classified on the basis of:
a) Number of terms – Monomial, Binomial, and Trinomial

- Monomial – A polynomial with one term. Example: 2x and 9xy - Binomial – A polynomial with two terms. Example: 3x²+ x, 9x + 4 - Trinomial – A polynomial with three terms. Example: 7x²+ 9x + 2

b) Degree of the polynomial – Linear Polynomial, Cubic Polynomial and Quadratic Polynomial

- Linear Polynomial – A polynomial with degree equal to one. For example, 9x + 7 is a linear polynomial.

- Quadratic Polynomial – A polynomial with its degree as two. For example, 5x²+ 2x + 1 is a quadratic polynomial.

- Cubic Polynomial – A polynomial with its degree as three. For example, 4x³+ 5x²+ 2x +16 is a cubic polynomial.
