3x3 - 5x2 + 7x - 18
Simplify ———————————————————
x - 2
Checking for a perfect cube :
3.1 3x3 - 5x2 + 7x - 18 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 3x3 - 5x2 + 7x - 18
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 7x - 18
Group 2: 3x3 - 5x2
Pull out from each group separately :
Group 1: (7x - 18) • (1)
Group 2: (3x - 5) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
