Types of Equations You Can Solve
1. Linear Equations
Equations of the form ax + b = 0. These have exactly one solution unless they are inconsistent.
2. Quadratic Equations
Equations of the form ax² + bx + c = 0. These may have two real roots, one real root, or complex roots.
3. Polynomial Equations
Higher-degree equations such as cubic (x³), quartic (x⁴), and beyond.
4. Rational Equations
Equations involving fractions, such as (x + 1)/(x - 2) = 3.
5. Exponential and Logarithmic Equations
Equations like 2^x = 8 or log(x) = 3.
6. Trigonometric Equations
Equations involving functions like sin(x), cos(x), tan(x), etc.
7. Systems of Equations
Multiple equations solved simultaneously to find values of variables that satisfy all conditions.
How to Use the Math Equation Solver

Example Equations and Solutions
Example 1: Linear Equation
Equation: 3x - 6 = 9
Solution: Add 6 to both sides → 3x = 15
Divide by 3 → x = 5
Example 2: Quadratic Equation
Equation: x² - 5x + 6 = 0
Factor: (x - 2)(x - 3) = 0
Solutions: x = 2, x = 3
Example 3: Exponential Equation
Equation: 2^x = 16
Rewrite 16 as 2⁴ → 2^x = 2⁴
x = 4
Example 4: Logarithmic Equation
Equation: log(x) = 2
Convert to exponential: x = 10² = 100
x = 100
Example 5: Trigonometric Equation
Equation: sin(x) = 0.5
x = π/6, 5π/6 + 2nπ (n ∈ Z)
Tips for Using the Math Equation Solver
- Use parentheses to group terms properly.
- Double-check your syntax before solving.
- For multi-variable equations, use commas to separate.
- Use built-in functions like sin(), cos(), log(), ln(), sqrt(), etc.
- Use scientific notation when dealing with very large/small numbers (e.g., 1e6 for 1,000,000).
Understanding Step-by-Step Solutions
Each solution includes a breakdown of the algebraic or numerical steps taken to solve the equation. This helps students learn and teachers to explain methods more effectively.
