You can put this solution on YOUR website! 24 -4a +6b -ab
.
This factoring is called grouping, and is possibly the hardest type
.
4 ( 6-a) + b ( 6-a)
.
(4+b) (6-a)
.
checking FOIL answer, 24 -4a +6b -ab
.
review carefully,,,usually the next to last step is hardest to visualize, but try
.
a c +b c = (a+b) (c) , above c is just (6-a)
