What is the Binomial Theorem?

Back

The Binomial Theorem provides a formula for expanding expressions of the form (a + b)^n, where n is a non-negative integer. It states that (a + b)^n = Σ (n choose k) * a^(n-k) * b^k for k = 0 to n.

What is Pascal's Triangle?

Back

Pascal's Triangle is a triangular array of the binomial coefficients. Each number is the sum of the two directly above it. It is used to find coefficients in the expansion of (a + b)^n.

How do you expand (a + b)^n using the Binomial Theorem?

Back

To expand (a + b)^n, use the formula: (a + b)^n = Σ (n choose k) * a^(n-k) * b^k for k = 0 to n.
