Answer
A
6 p cubed plus 29 p squared minus 22 p plus 21
B
6 p cubed plus 29 p squared plus 22 p minus 21
C
6 p cubed plus 29 p squared minus 34 p plus 21
D
6 p cubed plus 29 p squared plus 34 p minus 21
Explanation
Distribute each term in 2p + 7 across 3p² + 4p − 3. This gives 6p³ + 8p² − 6p + 21p² + 28p − 21. Combine like terms to get 6p³ + 29p² + 22p − 21, which is choice B.
