1. Use Pascal's Triangle to expand the binomial.

(d - 3) 6

d6 - 18d5 + 135d4 - 540d3 + 1,215d2 - 1,458d + 729

d6 + 18d5 + 135d4 + 540d3 + 1,215d2 + 1,458d + 729

d6 - 6d5 + 15d4 - 20d3 + 15d2 - 6d + 1

d6 + 6d5 + 15d4 + 20d3 + 15d2 + 6d + 1

2. Use the Binomial Theorem to expand the binomial. (3v + s) 5

s5 - 5s4v + 10s3v2 - 10s2v3 + 5sv4 - v5

s5 + 15s4v + 90s3v2 + 270s2v3 + 405sv4 + 243v5

s5 + 45s4v + 270s3v2 + 810s2v3 + 1,215sv4 + 729v5

s5 + 15s4 + 90s3 + 270s2 + 405s + 243
