:
((2x3 - 7x2) - 7x) + 2 = 0
STEP

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