Question 307941
First, multiply the two expressions together using the FOIL method: x^2+x-2x-2=4

Now set the equation equal to 0 by subtracting 4 from both sides: x^2+x-2x-6=0

Now we can do some simplifying: x^2-x-6=0
               
You can factor from here I think but here you go: (x-3)(x+2)

Hope this helps
