An equation solver finds the values of variables that satisfy mathematical equations. From simple linear equations to complex quadratic and polynomial equations, this tool helps you solve algebraic problems quickly and accurately. Whether you're a student checking homework, a teacher preparing lessons, or a professional solving real-world problems, an equation solver is an indispensable resource.
Linear equations (ax + b = 0) have one solution, quadratic equations (ax² + bx + c = 0) can have up to two solutions, and higher-degree polynomials can have multiple solutions. The equation solver uses proven mathematical methods like the quadratic formula, factoring, and numerical approximation to find exact or approximate solutions.
Solving 2x² - 5x + 2 = 0: a=2, b=-5, c=2. Discriminant: (-5)² - 4(2)(2) = 25 - 16 = 9. x = [5 ± √9] / 4 = [5 ± 3] / 4. Solutions: x = 2 or x = 0.5. Checking: 2(2)² - 5(2) + 2 = 8 - 10 + 2 = 0 ✓
