... The worst part is I'm decent with math by US standards in school and couldn't even solve the middle school one with a quick glance.

Multiply the top by the bottom to erase it. Reverse the square root of something. + Or - threw me right off...

Cause the middle school one is the quadratic formula. You use it to factor 2nd degree polynomials. You don't solve for a, b, and c, you just plug them in.

It is the quadratic formula. It already is the solution. The problem is any quadratic of the form ax²+bx+c=0
