Question

Need answer quick and simple explanation

Answer 1

(x + 2)(x + 2)(x + 2)
(x^2 + 4x + 4)(x + 2)
x^3 + 4x^2 + 4x + 2x^2 + 8x + 8
Simplify
Solution: x^3 + 6x^2 + 12x + 8
The answer is A

Answer 2

Answer:

A

Step-by-step explanation:

Given

(x + 2)³

= (x + 2)(x + 2)(x + 2) ← expand second/third factor using FOIL

= (x + 2)(x² + 4x + 4) ← distribute

= x(x² + 4x + 4) + 2(x² + 4x + 4) ← distribute both parenthesis

= x³ + 4x² + 4x + 2x² + 8x + 8 ← collect like terms

= x³ + 6x² + 12x + 8 → A
