Expanding a binomial to the 5th power with pascals triangle

The video tutorial explains how to use Pascal's Triangle to find terms in polynomial expansions. It covers the concept of monomials, handling negative terms, and specifically finding the fourth term in an expansion. The tutorial also demonstrates using Pascal's Triangle to determine coefficients for polynomial terms.

Explain the pattern observed in the terms of the expansion.

What is the significance of the coefficients 1, 5, 10, and 10 in the context of the problem?
