Solving a cubic equation using Cubic Equation Solver

Our cubic equation solver solves a cubic equation and give detailed solutions. Wherever possible all the 3 roots are given including the complex roots. The cubic equation solver shows detailed solutions in the following steps

  1. Finding the first root by using the factor theorem
  2. Using long division to find the quadratic expression
  3. Using either completing the square or factoring or quadratic formula to solve the quadratic equation


If the solver cannot find the first root through factor theorem, then a cubic formula may be used to solve your cubic equation
