The document provides a 4-step guide to multiplying a binomial and a trinomial. It involves drawing a box and labeling the terms, multiplying corresponding terms and adding exponents, ordering the terms by exponent, and combining like terms if any exist. The example problem is (9n^9 +7n^5 +5)+(3n^3 +2) and the full worked out solution is provided.

1. Guide to Multiplying a Binomial and a Trinomial (9n 9 +7n 5 +5)+(3n 3 +2)

2. Step 1: (First you have to draw your box and label the top and the side of the box with the numbers from the problem) 9n 9 +7n 5 +5 3n 3 +2

3. Step 2: (Then you multiply the numbers from the top of the boxes by the ones from the side of the box and add the exponents according to how they are lined up. 9n 9 +7n 5 +5 3n 3 +2 10 14n 5 18n 9 10n 3 21n 8 27n 12

4. Step 3: (Next you look at the numbers inside of the box and put them in order from the greatest exponent to the least exponent. 9n 9 +7n 5 +5 3n 3 +2 27n 12 +18n 9 +21n 8 +14n 5 +10n 3 +10 10 14n 5 18n 9 10n 3 21n 8 27n 12

5. Step 4: (Finally you look to see if you have any like terms in the problem. In this one I don’t have no like terms so I’m finish. 9n 9 +7n 5 +5 3n 3 +2 27n 12 +18n 9 +21n 8 +14n 5 +10n 3 +10 10 14n 5 18n 9 10n 3 21n 8 27n 12
