Question Analysis
This question tests the student's ability to apply the distributive property to two separate polynomial expressions and then combine like terms, which is a more complex application of polynomial multiplication.

Key Concept Explanation
The distributive property is used to multiply each term in the first polynomial by and each term in the second polynomial by . After distributing, the resulting terms are combined to simplify the expression.

Step-by-step Solution
1. Distribute to each term in the first polynomial:
2. Distribute to each term in the second polynomial:
