Answer 1

Could you factor 2x^2+13x+15?

Answer 2

What would you do first?

Answer 3

Part 1

Answer 4

If you had to factor that trinomial, what would you do first?

Answer 5

Wouldn't you multiply 2 by 15 first?

Answer 6

There is the problem. The directions say to put it in a form so that it can be factored by grouping.

Answer 7

So the first thing you should do is multiply 2 by 15. That would be 30. Then you find two factors of 30 whose sum is 13. What are they?

Answer 8

Yes. So replace 13x with 10x + 3x
