expand the following​

Answer 1

$(x + 2) {}^{ 3} = {x}^{3} + {2}^{3} + 3 \times x \times 2(x + 2) \\ = x {}^{3} + 8 + 6x(x + 2)$

Answer 2

Answer:

(x + 2)³ = x³ + 6x² + 12x + 8

Step-by-step explanation:

=> (x + 2)³

By using the formula of (a + b)³.

°.° (a + b)³ = a³ + b³ + 3ab(a + b)

=> (x + 2)³

=> x³ + 2³ + 3 × x × 2(x + 2)

=> x³ + 8 + 3x × 2(x + 2)

=> x³ + 8 + 6x(x + 2)

=> x³ + 8 + 6x² + 12x

=> x³ + 6x² + 12x + 8

.°. (x + 2)³ = x³ + 6x² + 12x + 8 ANSWER
