You can put this solution on YOUR website! For:
2x^2+12x+3x+18
.
Notice that of there is NO common factor for the four terms. The idea is to group terms together so there is a common factor.
.
Grouping:
(2x^2+12x) + (3x+18)
.
Now, factor each "sub group":
2x(x+6) + 3(x+6)
.
Between the two terms above, the common factor is (x+6), factor it out:
(x+6)(2x+3)
