Online Graphing Calculator (2D Function Plotter)

Plot equations, examine coordinates, and visualize mathematical functions in real-time

Algebra & Matrix Engine

Algebra & Matrix Studio

Solve quadratic equations with complex roots, 2x2 systems via Cramer's rule, binomial FOIL expansions, and 2x2/3x3 matrix linear algebra with instant proofs.

Quadratic Coefficients

Standard form: ax² + bx + c = 0 (where a ≠ 0).
Sample Presets:

Parabola Geometry

Factored Form: (x - 3)(x - 2) = 0

Step-by-Step Derivation (Quadratic Formula)

1Equation: 1x² - 5x + 6 = 0
2Discriminant Δ = b² - 4ac = (-5)² - 4(1)(6) = 1
3Δ > 0: Two distinct real roots.
4x₁ = (-(-5) + √1) / (2 × 1) = 3
5x₂ = (-(-5) - √1) / (2 × 1) = 2
