Solve for x

How It Works

Linear Equations

Equations of the form ax + b = c. Isolate x by moving constants to one side and dividing by the coefficient. One solution.

Quadratic Equations

Equations of the form ax² + bx + c = 0. Solved using the quadratic formula. Can have 0, 1, or 2 real solutions depending on the discriminant.

Rearranging

The solver moves all terms to one side (left - right = 0) to put the equation in standard form, then applies the appropriate solving method.

Complex Roots

When the discriminant is negative, the equation has complex (imaginary) roots of the form a + bi, where i = √(-1).
