Equation Solver

Solve linear and quadratic equations step by step

Quick answer

Linear equations have one solution, while quadratic equations can have zero, one, or two real solutions depending on the discriminant (b² - 4ac).

Formula

Linear: ax + b = 0 → x = -b/a | Quadratic: ax² + bx + c = 0 → x = (-b ± √(b² - 4ac)) / 2a

Solve Your Equation

Enter linear equation(e.g., 2x + 3 = 7)

Linear: ax + b = 0 → x = -b/a | Quadratic: ax² + bx + c = 0 → x = (-b ± √(b² - 4ac)) / 2a

Linear equations have one solution, while quadratic equations can have zero, one, or two real solutions depending on the discriminant (b² - 4ac).
