Question

1....classify the following as linear,quadratic and cubic polynomials:
a....2x-4-x³
b....x+4
c....4x÷2x²
d.....7t
2.....find the cofficient of x² in ( x²+2)³
plzz solve the questions ​

Answer 1

Answer:

1) classify the following as linear,quadratic and cubic polynomials:

a. 2x-4-x³ : Cubic Polynomial

b. x+4 : Linear Polynomial

c. 4x÷2x² = 2x^-1 = 2/x : Linear Polynomial

d. 7t : Linear Polynomial

2) Find the coefficient of x² in (x²+2)³

= (x²+2)³

= (x²)³ + 2³ + 3(x²)²(2) + 3(x²)(2)²

= x⁶ + 8 + 6x⁴ + 12x²

Coefficient of x² is 12.
