Radical expressions in mathematics involve square roots, cube roots, and the like. Simplifying radicals and working with radical expressions are important!

What is the Binomial Theorem? This algebraic tool is perhaps one of the most useful and powerful methods for dealing with polynomials! The Binomial Theorem shows how to expand any whole number power of a binomial — that is, (x + y)n — without having to multiply everything out the long way. The Binomial Theorem […]
