I have a review sheet in math for the final, and one of the questions says to find the answer to the quadratic equation all three ways. The three ways are quadratic formula (I did), factoring (I did), and completing the square, does anyone know how to do "Completing the square" method, I forgot how and didn't bring my text book home, if anyone can help that'd be great and I'd rep+. If it'd help to have a problem it's: X^2+5x+6=0, if you don't wanna give me the answer but just show me, that's fine, I just need help, and besides I already did that equation two other ways anyway.
