minus-squareChaoticNeutralCzech@feddit.orglinkfedilinkEnglisharrow-up2·20時間前Do you have a truly universal method for quadratic expansion that is easier to remember and compute than the formula? Don’t get me wrong, I enjoy quadratic expansion and always give it a few shots before resorting to the formula.

They’re the coefficients of a quadratic equation! Y = ax^2 + bx + c
0 = ax^2 + bx + c
