Question

what is a binomial theorem

Answer 1

In elementary algebra, thebinomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.

Answer 2

The Binomial Theorem is a quick way (okay, it's a less slow way) of expanding (or multiplying out) a binomial expression that has been raised to some (generally inconveniently large) power.

For instance, theexpression (3x – 2)10 would be very painful to multiply out by hand.
