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.
Fill in the required fields to see your result.
Algebra
Quadratic Formula Calculator
Finds all real solutions to any quadratic equation of the form ax² + bx + c = 0. Use it when factoring is difficult or impossible and you need exact roots fast.
