Homework Help: Algebra II

Posted by Rachelle on Wednesday, November 12, 2008 at 4:51pm.

I am expected to use the quadratic equation for the following: x2 + 3x 4 = (x + 4)(x 1) = 0. Once this is plugged into the value of x (the long equation, which I am unable to copy from the internet, but it goes -3 plus or minus the square root of...) I got
-8/2, but I am also supposed to get 2/2. How do you get 2/2? Thanks!!
