Answer:
(x + 6) • (x + 2) • (x - 4)
Step-by-step explanation:
STEP
1
:
Equation at the end of step 1
(((x3) + 22x2) - 20x) - 48
STEP
2
:
Checking for a perfect cube
2.1 x3+4x2-20x-48 is not a perfect cube
Trying to factor by pulling out :
2.2 Factoring: x3+4x2-20x-48
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: x3-48
Group 2: 4x2-20x
Pull out from each group separately :
Group 1: (x3-48) • (1)
Group 2: (x-5) • (4x)
