Solve for x by factoring. check your answers. can you check to see if i'm correct? 4) x^2 - 4x - 12 = 0 (x - 6)(x + 2)

If you want to check if your answer is correct, expanding it all out will help!

(x-6)(x+2)=0 <-- Use FOIL tactic 

x²+2x-6x-12=0

x²-4x-12=0 

As you can see, this is identical to the initial equation given. The x values would be 6 and -2, as seen from the factored equation. 

Hope I helped :) 

hope it is correct if not i'm srry i tried to
