What is Equation Solver?
Equation Solver is a free online mathematical tool that helps you solve linear and quadratic equations step by step. This tool provides instant, accurate results with detailed breakdowns and visual charts to help you understand the numbers behind the calculation.
Formula Used
The Equation Solver uses the following formulas:
Linear: ax + b = 0 → x = -b/a. Quadratic: ax² + bx + c = 0 → x = (-b ± √(b² - 4ac)) / 2a. The discriminant D = b² - 4ac determines the nature of roots.
The calculation is performed automatically when you click the Calculate button, ensuring error-free results every time.
