Question

Classify the following as linear, quadratic and cubic polynomials:
(i) x² + x
(ii)x - x3
(iii) y + y2 +4 (iv) 1 + x
(v) 31
(vi)r 2
(vii) 783​

Answer 1

Answer:

i) quadratic

ii) cubic

iii) quadratic

iv) linear

v) zero polynomial

vi) zero polynomial

vii) zero polynomial

Answer 2

Solution :-

(i) x² + x = Quadratic polynomial

(ii) x – x³ = Cubic polynomial

(iii) y + y² + 4 = Quadratic polynomial

(iv) 1 + x = Linear Polynomial

(v) 3t = Linear polynomial

(vi) r² = Quadratic polynomial

(vii) 7x³ = Cubic polynomial

Note :-

If degree is 1 then it is called linear polynomial, if degree is 2 then it is called quadratic polynomial and if degree is 3 then it is called cubic polynomial.

Hope it helps you !!!
