Equation Solver
Solve linear, quadratic, and polynomial equations
How to use this tool
Type an equation that equals zero, like x² - 5x + 6 = 0. Use ^ for powers (x^2 = x squared).
Click an example below to try a sample. The tool finds every value of x that makes the equation true (the roots).
Don't know how to type it? Switch to Coefficients mode and just enter the numbers in front of each term.
x = variable, ^ = power— 2x^2 + 3x - 5 = 0
