Factors of an Equation Formulas

1. MX + MY = M(X + Y)
2. X^{2}  Y^{2} = (X  Y)(X + Y)
3. X^{3}  Y^{3} = (X  Y)(X^{2} + XY + Y^{2})
4. X^{3} + Y^{3} = (X + Y)(X^{2}  XY + Y^{2})
5. (X + Y)^{2} = X^{2} + 2XY + Y^{2}
6. (X  Y)^{2} = X^{2}  2XY + Y^{2}
7. (X + Y)^{3} = X^{3} + Y^{3} + 3XY(X + Y)
8. (X  Y)^{3} = X^{3}  Y^{3}  3XY(X  Y)
9. (X + Y + Z)^{2} = X^{2} + Y^{2} + Z^{2} + 2XY + 2YZ + 2ZX
