Question

Classify the following as linear, quadratic and cubic polynomials:
(i) 2x^3 + x
(ii) 5x − x^2 + 7
(iii) 100
(iv) 5t − √2
(v) m^2 + 9m – 2
(vi) 2x
(vii) x^3 + x^2 + x +1

Answer 1

Answer:

if the highest degrees is 3 it is cubic polynomial

if it is 2 quadratic polynomial

if it is 1 linear

Step-by-step explanation:

linaer

2x

5t-√2

quadratic

5x-x^2+7

m^2+9m-2

cubic

2x^3+x

x^3+x^2+x+1

Answer 2

Answer:

(i) 2x^3 + x                - Cubic polynomial

(ii) 5x − x^2 + 7         - Quadratic polynomial

(iii) 100                      -Linear Polynomial

(iv) 5t − √2                - Linear Polynomial

(v) m^2 + 9m – 2      - Quadratic polynomial

(vi) 2x                        - Linear Polynomial

(vii) x^3 + x^2 + x +1 - Cubic Polynomial
