Look for patterns.Each expansion is a polynomial. There is one more term than the power of the exponent, n. That is, there are terms in the expansion of (a + b)n.2. But, before we begin describing Pascals Triangle Binomial Expansion Calculator Pascal triangle pattern is an expansion of an array of binomial coefficients. It is especially useful when raising a binomial to lower degrees. You can also get the final expansion at one click if you expand using Pascal’s triangle calculator. For a binomial expansion with a relatively small exponent, this can be a straightforward way to determine the coefficients. Example 1 : Expand the following using pascal triangle (3x + 4y) 4. So instead of doing a plus b to the fourth using this traditional binomial theorem-- I guess you could say-- formula right over here, I'm going to calculate it using Pascal's triangle and some of the patterns that we know about the expansion.
