Quadratic Formula Solver

Solve any quadratic equation of the form ax² + bx + c = 0 instantly. Use this when factoring is difficult or impossible and you need exact roots fast.

Coefficient a (x²)

Coefficient b (x)

Constant c

Solution Type

Fill in the required fields to see your result.

Algebra

Linear Equation Solver

Solve any single-variable linear equation of the form ax + b = 0 for the unknown x. The simplest non-trivial equation in algebra, this is the building block for systems of equations, slope-intercept lines, and almost every applied modelling problem.
