In your notebook, set up the following addition using a vertical format and find the sum of the given polynomials. 7b + 3, -4b + 5 and -3+2 a.) 10b + 2 b.) 10 c.) 0 d.) b - 8 explain.

Terms containing b are added; terms not containing b are added. The sum of the b terms is 0, because 7-4-3 = 0. That leaves only the constant 3+5+2=10.

Selection B properly describes the sum.
