Is it possible to combine 2x squared with 9x?

Not sure how to tackle solving this one.

**Ali**, Wednesday, April 10, 2013 at 10:55pmOn these types of questions I always like to do the opposite of the FOIL (First Outer Inner Last) method.

Since the first coefficient is 2 we know we have to have a 2x and an x and then the -5 at the end will result in only 5 and a 1 (one has to be postive and one has to be negative).

This leaves you with

(2x and 1)(x and 5)

OR

(2x and 5)(x and 1)

By process of elimination, I figured out it was (2x+1)(x-5)=0.

You can then set each equation equal to 0 and solve for x.
