Answer:
A) y^3+27
Step-by-step explanation:
There are two ways of solving this problem:
1. Recognizing this as the factored form of the sum of perfect cubes
2. Distribute and add the like terms.
1. In order to distribute we must multiply y by y^2-3y+9, and then 3 by y^2-3y+9:


After we add the positive and negative 3y^2 and 9y, they will cancel out and be gone entirely:

2. You know how you can factor the difference of perfect squares?
As an example:

Well, not many people know this but you can actually factor both the sum and difference of perfect cubes:


Because we have these identities, we can easily establish here that we have the sum of perfect cubes, and that (y+3)(y^2-3y+9)= y^3+3^3 = y^3+27
