Algebra is the foundation of nearly all advanced mathematics — from engineering and physics to economics and data science. Whether you are solving for x in a linear equation, factoring a quadratic, or simplifying a complex rational expression, an Algebra Calculator can show you the steps so you learn the process while getting the answer.
Types of Algebra Problems You Can Solve
| Problem Type | Example | Solution Method |
|---|---|---|
| Linear equations | 3x + 7 = 22 | Subtract 7, divide by 3 → x = 5 |
| Systems of equations | 2x + y = 10, x − y = 2 | Substitution or elimination → x = 4, y = 2 |
| Quadratic equations | x² − 5x + 6 = 0 | Factor: (x−2)(x−3)=0 → x = 2, 3 |
| Factoring polynomials | 6x² + 11x − 10 | AC method → (3x − 2)(2x + 5) |
| Rational expressions | (x² − 1)/(x − 1) | Factor numerator, cancel → x + 1 (x ≠ 1) |
Use the Algebra Calculator to check your work or learn step-by-step solutions.
Step-by-Step: Solving a Quadratic Equation
Let’s walk through x² − 5x + 6 = 0 manually:
- Identify coefficients: a = 1, b = −5, c = 6
- Find factors of ac = 6 that add to b = −5: −2 and −3
- Rewrite: x² − 2x − 3x + 6 = 0
- Group: x(x − 2) − 3(x − 2) = 0
- Factor: (x − 2)(x − 3) = 0
- Solve: x = 2 or x = 3
You can verify your answer with the Algebra Calculator — it shows each step so you can check where you went wrong.
Common Algebra Mistakes to Avoid
- Distributing incorrectly: Remember that −(x + 3) = −x − 3, not −x + 3
- Dividing by zero: If a denominator has x, make sure your solution doesn’t make it zero
- Sign errors: When moving terms across the equals sign, the sign changes. 2x + 3 = 7 → 2x = 7 − 3
- Incomplete factoring: Always check if you can factor further, especially common factors first
When to Use an Algebra Calculator
