False
4x^2+7x^2+x^2=12x^2 not 11x2
Factoring: x4-4x3+8x-32
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 8x-32
Group 2: -4x3+x4
Pull out from each group separately :
Group 1: (x-4) • (8)
Group 2: (x-4) • (x3)
-------------------
Add up the two groups :
(x-4) • (x3+8)
