This one also factors.
I gave you the previous one, why don't you try this, the factors are quite simple.
Let me know what you got.

Reiny i got
(x+5)(x-3)
x=-5 or x=3
(x+5)(x-3)
x=-5 or x=3
Not quite. You have to get +2x^2
(2x-5)(x+3) ought to do it.
(2x-5)(x+3) ought to do it.
not 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
