Pulling out like terms
4.1 Pull out like factors :
16x3 - 24x2 - 28x - 6 =
2 • (8x3 - 12x2 - 14x - 3)
Checking for a perfect cube :
4.2 8x3 - 12x2 - 14x - 3 is not a perfect cube
Trying to factor by pulling out :
4.3 Factoring: 8x3 - 12x2 - 14x - 3
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -14x - 3
Group 2: 8x3 - 12x2
Pull out from each group separately :
Group 1: (14x + 3) • (-1)
Group 2: (2x - 3) • (4x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
