Equation solver
General equation solver – type any equation and get the solution.
Supported: +, −, ×, power via ^ (e.g. x^2), no brackets. The unknown is always x.
Type an equation with the unknown x – the solver recognises and solves it.
How the solver works
You type an equation with the unknown x on both sides of the equals sign. The solver moves everything to one side (into the form ax² + bx + c = 0), combines like terms, and based on whether the x² coefficient is non-zero, recognises whether it's a linear or quadratic equation – and solves it.
What you can enter
- Linear: 2x + 3 = 7, 3x − 5 = x + 7
- Quadratic: x^2 − 5x + 6 = 0, 2x^2 = 8
- Squares are written with a caret: x^2
- Multiplication is implicit: 2x means 2·x
For a detailed breakdown with a graph, use the dedicated linear equation or quadratic equation calculator.
Note: the solver handles linear and quadratic equations with one unknown x. Brackets and fractions are not yet supported.
