About the Equation Solver
The equation solver allows you to enter your algebra problems and get step-by-step solutions. It can solve linear equations, quadratic equations, polynomial equations, and more.
How to Use the Equation Solver
To solve your equation using the equation solver:
- Type in your equation like 2x+3=7
- Specify the variable you want to solve for (default is x)
- Click the "Solve" button to get started
- The solver will then show you the steps to help you learn how to solve it on your own
Supported Equation Types
The equation solver can handle various types of equations:
- Linear equations: 2x + 3 = 7, x - 5 = 10
- Quadratic equations: x² - 4 = 0, 2x² + 3x - 5 = 0
- Polynomial equations: x³ + 2x² - x - 2 = 0
- Absolute value equations: |x - 3| = 5
- Radical equations: √(2x + 3) = 5
Solving Equations Step-by-Step
Learning algebra is about understanding the "how" and "why" behind solving equations. Our solver shows you each step with explanations so you can learn as you go:
- Simplify: Combine like terms and simplify both sides
- Isolate: Get the variable terms on one side and constants on the other
- Solve: Divide or use other operations to solve for the variable
- Check: Verify your solution by plugging it back into the original equation
Graphing Equations
For equations with one variable, the solver will also show a graph of the equation to help visualize the solution. The x-intercept(s) on the graph correspond to the solution(s) of the equation.
