Question 16814: Could someone help me please with this problem?
I am having a meltdown with trinomials and factoring.
I am supposed to factor each trinomial using trial and error, I am STUCK!:
15x^2-x-2 and 15x^2 + 13x-2
Thank you in advance and all help is appreciated!

Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
1) Factor:

What are the factors of 15x^2?

What are the factors of -2?

Now you can use trial & error. Pick a pair of factors from the first list and a pair of factors from the second list.
But keep in mind that you want the right combination that will make a (-x) for the middle term of your trinomial.
Try: = Oops!
Almost...but no cigar! Try switching the -1 and the 2
= Not quite!
You need a -x not a +x
Try = Bingo!
Now try this approach on your second problem.
