Equation Solver
Solve linear and quadratic equations step by step.
Enter your equation coefficients to find the solution with detailed working.
Solution
Linear Equation: ax + b = 0
x = -b / a
Quadratic Equation: ax² + bx + c = 0
x = (-b ± √(b² - 4ac)) / 2a
System of Two Linear Equations:
a₁x + b₁y = c₁
a₂x + b₂y = c₂
Solved using Cramer’s Rule or substitution.
Tips:
- A linear equation has exactly 1 solution (if a ≠ 0)
- A quadratic can have 0, 1, or 2 real solutions depending on the discriminant
- The discriminant (b²-4ac) tells you how many real solutions exist
