In algebra a quadratic equation from the Latin quadratus for square is any equation that can be rearranged in standard form as where x represents an unknown and a b and c represent known numbers where a 0. The discriminant is 3 2 4 7 0 2 8 9 1 7 2 displaystyle 324cdot 70289172 3 2 4 7 0 2 8 9 1 7 2. Solving that yields 2 2 u 2 5 or u 2 9 so u 3 works.
In the first of the two equations displaystyle x-12 and in the second.
