Question

Classify the following polynomials as linear, quadratic, cubic and biquadratic polynomials:

(i) x + x² + 7y²

(ii) 3x - 2

(iii) 2x + x²

(vi) 7t⁴ + 4t³ + 3t - 2

Answer 1

Given polynomial,

(i) x + x² + 7y² is quadratic as degree of polynomial is 2.

(ii) 3x - 2 is linear as degree of polynomial is 1.

(iii) 2x + x² is quadratic as degree of polynomial is 2.

(iv) 3y is linear as degree of polynomial is 1.

(v) t² + 1 is quadratic as degree of polynomial is 2.

(vi) 7t⁴ + 4t³ + 3t - 2 is bi-quadratic as degree of polynomial is 4.
