What is the Equation Solver?
Type an equation like 2x + 5 = 17, x^3 - 6x = 4 or sin(x) = 0.5 and the solver finds every real value of x in the range you choose. It scans the range, narrows each root down with bisection, and shows the left and right side values so you can check the answer yourself.
How to use the Equation Solver
- Type the equation with an = sign (use * for multiply, e.g. 2*x).
- Adjust the search range if roots are outside -100 to 100.
- See all roots and the check values.
Does it find complex roots?
This tool finds real roots only. For complex roots of polynomials, use the Polynomial Roots Calculator.
This Equation Solver is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
