Multiply the top by the bottom to erase it. Reverse the square root of something. + Or - threw me right off…
minus-squareGiveMemes@jlai.lulinkfedilinkarrow-up32·1 年前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.
minus-squareXavienth@lemmygrad.mllinkfedilinkarrow-up5·1 年前It is the quadratic formula. It already is the solution. The problem is any quadratic of the form ax²+bx+c=0
