Binomial Theorem




 

Videos, solutions, and lessons to help High School students know and apply the Binomial Theorem for the expansion of (x + y)n in powers ofx and y for a positive integer n, where x and y are any numbers, with coefficients determined for example by Pascal’s Triangle.

Suggested Learning Targets


  • For small values of n, use Pascal's Triangle to determine the coefficients of the binomial expansion.
  • Use the Binomial Theorem to find the nth term in the expansion of a binomial to a positive power.
