Best ResponseYou've already chosen the best response.0Ok. Sorry I had to leave. But the general equation is ax^2+bx+c So you get a*c. And you cut the bx into 2 numbers that add up to your a*c. Then you will eventually end up with (x+something)(x+something). And your answers are whatever makes the equation zero.
