Pascal’s Triangle
Pascal’s triangle is a geometric arrangement of the binomial coefficients in the shape of a triangle. In Pascal’s triangle, each number in the triangle is the sum of the two digits directly above it. In Algebra II, we can use the binomial coefficients in Pascal’s triangle to raise a polynomial to a certain power.

Binomial Theorem
In Algebra II, the binomial theorem describes the explanation of powers of a binomial. When expanding a binomial, the coefficients in the resulting expression are known as binomial coefficients and are the same as the numbers in Pascal’s triangle. By using the binomial theorem and determining the resulting coefficients, we can easily raise a polynomial to a certain power.
