Equation at the end of step

2

:

((2x3 + 7x2) - 12x) - 45 = 0

STEP

3

:

Checking for a perfect cube

3.1 2x3+7x2-12x-45 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 2x3+7x2-12x-45

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -12x-45

Group 2: 2x3+7x2

Pull out from each group separately :

Group 1: (4x+15) • (-3)

Group 2: (2x+7) • (x2)
