+65 The quadratic formula is a general formula used for solving the quadratic equation: x = − b ± b 2 − 4 a c 2 a . Note that: if x2 = k, where k ≥ 0, then or same as x = ± k , where ± means “plus or minus.”
+36916 The Quadratic Formula is a method of calculating the value(s) of 'x' that solve the quadratic of form
y = a x2 + b x + c the x values can be found by plugging a , b and c into the formula and computing:
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
