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 Inequality Solver
Solve linear inequalities of the form ax + b < c (or ≤, >, ≥) and express the answer as an interval or number line. Use it when solving algebraic inequalities in coursework or real-world constraint problems.
