WebStep 1: Enter the equation you want to solve using the quadratic formula. The Quadratic Formula Calculator finds solutions to quadratic equations with real coefficients. For equations with real solutions, you can use the graphing tool to visualize the solutions. Quadratic Formula: x = −b±√b2 −4ac 2a x = − b ± b 2 − 4 a c 2 a. Web2 Answers. Note that f(x) = ecx is a solution if c = eca. This can be solved for c in terms of the Lambert W function: c = − W( − a) / a. The Lambert W function has infinitely many branches, each of which gives a solution. There are two real solutions if 0 < a < 1 / e, one if a ≤ 0 or a = 1 / e, none if a > 1 / e.
