Answer:
D. 1/8xy(x^2 + 7y)
Step-by-step explanation:
You want to rewrite 1/8x^3y + 7/8xy^2 using a common factor.
Factors
The two terms have factors that can be identified as ...
- 1/8x^3y = (1/8)(x)(x)(x)(y)
- 7/8xy^2 = (7)(1/8)(x)(y)(y)
The factors that appear in both terms are (1/8)(x)(y), so we can factor that out:
= 1/8xy(x^2 +7y) . . . . . matches choice D
