Factoring

Special factorizations

Factor using formulas

factor by grouping

an + a + bn + b = a(n + 1) + b(n+1) = (a + b)(n + 1)

Formulas

Cubic equations

a^3 + b^3 = (a + b)(a^2 - ab + b^2)

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

Quadratic equations

a^2 + b^2 = (a + b)(a - b)

FOIL

Standard Form

ax + by = c

Slope Intercept Form
