Classification of polynomials on the basis of degree :

1. Constant : A polynomial is said to be constant if its degree (exponential power of variable) is 0.

Eg. - 12000, 123, 7 etc.

2. Linear : A polynomial is said to be linear if its degree (exponential power of variable) is 1.

Eg. - 2x, 7x + 5, 10y + 4 etc.

3. Quadratic : A polynomial is said to be quadratic if its degree (exponential power of variable) is 2.

Eg. - x², 3x² + 7, 7x² - 4x + 5, 9x² + √2x etc.

4. Cubic : A polynomial is said to be cubic if its degree (exponential power of variable) is 3.

Eg. - 8x³ + 6x² + 5x + 9, √2x³ etc.

Classification of polynomials on the basis of no. of terms :

1. Monomial : A polynomial is said to be monomial if its no. of term is 1.

Eg. - 2x, 1200, 7x³ etc.

2. Binomial : A polynomial is said to be binomial if its no. of terms is 2.

Eg. - 3x + 4, 10y + z etc.

3. Trinomial : A polynomial is said to be trinomial if its no. of terms is 3.

Eg. - 5x³ + 7x + 5 , 4y² + 5y + 4 etc.

4. Polynomial with four terms : A polynomial consisting of 4 terms.

Eg. 4x³ + 4x² + 4x + 5 etc.

Note : After trinomial, a polynomial containing 5, 8, 11 no. of terms are called as polynomial with 5 terms, polynomial with 8 terms, polynomial with 11 terms respectively. Name is given according to no. of terms.
