How do you factor trinomials?

Answer 1

you do 2 sets of parenthesis and check it.

for example:

w2(w squared)-7w-8

(w+1) (w-8)

*if you add 1w and -8w you will get -7w, which is what they want you to get. and w & w multiply to get w2(w squared), which is also what the factoring wants.

another example:

3w2 (3w squared)+2-8

(3w-4) (w+2)

*same thing applies with 3w x w = 3w2, and -4 +2=2, which is the answer. use this theory in all of them, unless there is a greatest common factor (GCF).
