Algebra Calculator & Expression Simplifier

Evaluate polynomials, expand binomial products using FOIL, and compute power-rule derivatives

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.

Algebra Mode

Expand binomial product: (a₁x + b₁)(a₂x + b₂)
Binomial 1 (a₁x + b₁)
Binomial 2 (a₂x + b₂)
Expanded Quadratic Form
(2x + 3)(1x - 4)
= 2x² - 5x - 12

FOIL Breakdown (First, Outer, Inner, Last)

F (First):First: (2x) × (1x) = 2x²
O (Outer):Outer: (2x) × (-4) = -8x
I (Inner):Inner: (3) × (1x) = 3x
L (Last):Last: (3) × (-4) = -12
