WebIn algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear, not quadratic.) The numbers a, b, and c are the coefficients of the equation ... WebMar 20, 2016 · so z = ± 3. The first equation gives a = ± 3 and the second b = 0. After substitution you can solve the first square to obtain: in other words: 2 a 2 + 2 a b i = 18. Now 18 is real, this mean: a = 0 or b = 0. If a = 0 then 0 = 18 which is false, so b = 0; then 2 a 2 = 18, so the solutions are a = ± 3. Correct.
