STEP 3: 9x3 + 12x2 - 23x - 18
Simplify —————————————————————
3x + 2
Checking for a perfect cube :
3.1 9x3 + 12x2 - 23x - 18 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 9x3 + 12x2 - 23x - 18
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -23x - 18
Group 2: 9x3 + 12x2
Pull out from each group separately :
Group 1: (23x + 18) • (-1)
Group 2: (3x + 4) • (3x2)
Step-by-step explanation:
The answer is A
