:

Checking for a perfect cube

3.1 8x3-12x2+18x-27 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 8x3-12x2+18x-27

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

Group 1: 18x-27

Group 2: -12x2+8x3

Pull out from each group separately :

Group 1: (2x-3) • (9)

Group 2: (2x-3) • (4x2)

-------------------

Add up the two groups :

(2x-3) • (4x2+9)
