y = mx + b
Standard Form
ax + by = c
Quadratic Equations
FOIL
Formulas
Quadratic equations
a^2 + b^2 = (a + b)(a - b)
Cubic equations
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
Special factorizations
factor by grouping
an + a + bn + b = a(n + 1) + b(n+1) = (a + b)(n + 1)
