Which equation would you like to solve?
"Solve the equation" is a bit general! I've built a tool below for common types like Linear and Quadratic equations. Select a tab, enter your numbers, and I'll show you the step-by-step solution and graph.
A linear equation describes a straight line. To solve it, we use inverse operations to isolate the variable x. Generally, we move the constant term to the other side by adding or subtracting, and then divide by the coefficient of x.
Quadratic equations describe a parabola. We solve them using the Quadratic Formula. The term inside the square root, b² - 4ac, is called the discriminant, which tells us if there are 2 real roots (positive), 1 real root (zero), or complex roots (negative).
