We’re so used to seeing binomials squared such as, (x-25)^2, and factoring and expanding them without a problem.  But what happens when our reliable binomials need to be expanded and simplified and are raised to the third power?  Luckily for us, there is a Rule for when this happens:
(a+b)^3=a^3+(3a)^2 b+(3ab)^2+b^3

What you’ll find in this video:
