Answer 2

Explanation:

STEP

1

:

Equation at the end of step 1

((2x3 + x2) - 16x) - 15

STEP

2

:

Checking for a perfect cube

2.1 2x3+x2-16x-15 is not a perfect cube

Trying to factor by pulling out :

2.2 Factoring: 2x3+x2-16x-15

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

Group 1: -16x-15

Group 2: 2x3+x2

Pull out from each group separately :

Group 1: (16x+15) • (-1)

Group 2: (2x+1) • (x2)
