Algebra
Quadratic Equation Solver
Finds real roots of any quadratic equation ax² + bx + c = 0 using the quadratic formula. Use it whenever you need to factor a parabola, find x-intercepts, or solve physics and engineering problems involving squared variables.
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.
