(4x-3) (3x²-1)
Step 1:Equation at the end of step 1 : (((12 • (x3)) - 32x2) - 4x) - 3
Step 2 :Equation at the end of step 2 : (((22•3x3) - 32x2) - 4x) - 3 Step 3 :Checking for a perfect cube :

3.1 12x3-9x2-4x-3 is not a perfect cube
3.2 Factoring: 12x3-9x2-4x-3
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -4x-3
Group 2: 12x3-9x2
Pull out from each group separately :
Group 1: (4x+3) • (-1)
Group 2: (4x-3) • (3x2)
