Quadratic formula if b is already negative

WebJan 10, 2015 · To answer your question, yes, the formula always works for quadratic equations, because from the equation a x 2 + b x + c = 0, one can derive the formula x = − b ± b 2 − 4 a c 2 a manually. Here is a video on Youtube showing such a derivation. The factors become imaginary numbers if b 2 − 4 a c < 0, which means b 2 − 4 a c is negative. WebA quadratic equation in "Standard Form" has three coefficients: a, b, and c. Changing either a or c causes the graph to change in ways that most people can understand after a little …
