Use Pascal's Triangle to complete the expansion of (p + q)^6. p^6 + ____p^5q + 15p^4q^2 + 20p^3q^3 + 15p^2q^4 + 6pq^5 + q^6

Explanation: Pascal's Triangle gives us the coefficients for the expansion of (p + q)^n. For n=6, the row is 1, 6, 15, 20, 15, 6, 1.Identifying Missing Term: We already have the coefficients for p^6, p^4q^2, p^3q^3, p^2q^4, pq^5, and q^6. We need the coefficient for p^5q.Finding Coefficient: The coefficient for p^5q is the second number in the 6th row of Pascal's Triangle, which is 6.Final Answer: So the missing term is 6p^5q.

\newline

(p + q)^6

p^6 +

____

p^5q + 15p^4q^2 + 20p^3q^3 + 15p^2q^4 + 6pq^5 + q^6

Explanation: Pascal's Triangle gives us the coefficients for the expansion of $(p + q)^n$ . For $n=6$ , the row is $1, 6, 15, 20, 15, 6, 1$ .
Identifying Missing Term: We already have the coefficients for $p^6$ , $p^4q^2$ , $p^3q^3$ , $p^2q^4$ , $pq^5$ , and $q^6$ . We need the coefficient for $p^5q$ .
Finding Coefficient: The coefficient for $p^5q$ is the second number in the $6$ th row of Pascal's Triangle, which is $6$ .
Final Answer: So the missing term is $6p^5q$ .
