Solve the quadratic equation 30 + x - x2 = 0 by factoring.

OpenStudy (luigi0210):

you mean 1

OpenStudy (luigi0210):

And that makes -x^2 positive

OpenStudy (jhannybean):

Yeah, nevermind. I guess you can only factor out the -1 :(

OpenStudy (jhannybean):

\[\large -1(x^2 -x-30)=0\]\[\large -(x-6)(x+5)=0\]

OpenStudy (jhannybean):

And then you just... solve for x.

OpenStudy (jhannybean):

@Luigi0210 you're a butt <_<
