Read each question carefully and show all your work. Use Pascal's Triangle or the Binomial Theorem to expand the given expressions.
Pascal's Triangle is a triangular array of the binomial coefficients. Each number is the sum of the two numbers directly above it.
Fill in the missing numbers in Pascal's Triangle below:
Row 0: 1
Row 1: 1 1
Row 2: 1 2 1
Row 3: 1 3 3 1
Row 4: 1 _ _ _ 1
Row 5: 1 _ _ _ _ 1
1. The coefficients in the expansion of (a + b)ⁿ are given by the triangle.
2. The binomial theorem provides a formula for expanding any power of a .
3. The sum of the exponents of a and b in each term of a binomial expansion is always equal to .
1. Expand (x + y)³ using Pascal's Triangle.
