Answer 1

Answer:

STEP

1

:

Equation at the end of step 1

((64 - 144a) + (108 • (a2))) - 33a3

STEP

2

:

Equation at the end of step

2

:

((64 - 144a) + (22•33a2)) - 33a3

STEP

3

:

Checking for a perfect cube

3.1 -27a3+108a2-144a+64 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: -27a3+108a2-144a+64

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

Group 1: -144a+64

Group 2: 108a2-27a3

Pull out from each group separately :

Group 1: (9a-4) • (-16)

Group 2: (a-4) • (-27a2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.
