Question

Solving/simplfying(a-2)(a+3)(a+2)

Answer 1

(a-2)(a+3)(a+2)

First, let's expand two brackets

(a-2)(a+2)

a(a+2) - 2(a+2)

a² + 2a - 2a - 4

evaluate

a² - 4

Next, use what we've gotten and then expand with the second bracket

(a² - 4 ) (a+3)

a² (a+3) -4(a+3)

a³+ 3a² - 4a - 12

Evaluate
