I gave you the previous one, why don't you try this, the factors are quite simple.

Let me know what you got.

(x+5)(x-3)

**bobpursley**, Sunday, December 28, 2008 at 2:30pmNot quite. You have to get +2x^2

(2x-5)(x+3) ought to do it.

**Reiny**, Sunday, December 28, 2008 at 2:30pmnot quite,

did you notice that the first term was 2x^2, so one of the factors must have started with 2x

so it had to be (2x...)(x....)

YOu should have expanded your answer to see if you get the original question back.

I got (2x-5(x+3)= 0

then

x = 5/2 or x = -3
