Answer:
(((3 • (x3)) - (2•5x2)) - x) - 12
((3x3 - (2•5x2)) - x) - 12
Checking for a perfect cube
3x3-10x2-x-12 is not a perfect cube
Trying to factor by pulling out :
Factoring: 3x3-10x2-x-12
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -x-12
Group 2: 3x3-10x2
Pull out from each group separately :
Group 1: (x+12) • (-1)
Group 2: (3x-10) • (x2)
Bad NEWS BAD NEWS: Factoring by pulling out fails.
