Factors of an Equation Formulas
1. MX + MY = M(X + Y)
2. X2 - Y2 = (X - Y)(X + Y)
3. X3 - Y3 = (X - Y)(X2 + XY + Y2)
4. X3 + Y3 = (X + Y)(X2 - XY + Y2)
5. (X + Y)2 = X2 + 2XY + Y2
6. (X - Y)2 = X2 - 2XY + Y2
7. (X + Y)3 = X3 + Y3 + 3XY(X + Y)
8. (X - Y)3 = X3 - Y3 - 3XY(X - Y)
9. (X + Y + Z)2 = X2 + Y2 + Z2 + 2XY + 2YZ + 2ZX
