Stuck on an equation? Paste it in and let the solver find the roots. This tool handles linear, quadratic, cubic, and polynomial equations as well as systems of linear equations. It returns exact symbolic solutions when possible and numerical approximations when needed.
For quadratic equations, the solver applies the quadratic formula and simplifies radicals automatically. Higher-degree polynomials are solved via factoring heuristics and numerical root-finding. Systems of linear equations use Gaussian elimination. Results are displayed step-by-step so you can follow the solution process and learn from it, not just copy an answer.
Solve assigned equations and review the steps to understand the method.
Quickly isolate a variable in a design equation without manual rearrangement.
Practice solving equations and verify your answers before an exam.
Solve break-even equations or interest-rate formulas symbolically.
For multiple variables, enter a system of equations (one per line). The solver uses elimination to find the solution set.
The solver will return complex number solutions (a + bi form) when the discriminant is negative.
Yes. Each major step is displayed so you can follow the logic from the original equation to the final answer.
