Formula reference
Linear
ax + b = 0
Quadratic
x = (-b ± √(b² - 4ac)) / 2a
Cubic
ax³ + bx² + cx + d = 0
Example: x² - 5x + 6 = 0
Choose equation type
Pick the degree you want to focus on.
Enter equation
Use standard algebraic notation. Supports x² and x^2.
We move all terms to the left side and solve for x.
How it works
- We normalize your equation into the standard form and identify coefficients.
- For quadratics, we compute the discriminant to classify the roots.
- For cubics, we approximate a real root and reduce the polynomial for remaining roots.

Equation tips
Linear
Solve by isolating x: x = -b/a.
Quadratic
Discriminant Δ = b² - 4ac tells the root type.
Cubic
Find a real root, then solve the remaining quadratic.
