Answer 3

To simplify the expression (y + 7) + (y + 2)(y - 7), you can use the distributive property to expand the second term and then combine like terms:

1. Start with the original expression:

   (y + 7) + (y + 2)(y - 7)

2. Use the distributive property to multiply (y + 2) by each term inside the parentheses (y - 7):

   y + 7 + y(y - 7) + 2(y - 7)

3. Distribute y and 2 into the parentheses:

   y + 7 + y^2 - 7y + 2y - 14

4. Combine like terms:

   (y - 7y + 2y) + (7 - 14) + y^2 + 7

5. Further simplify:

   -4y - 7 + y^2 + 7

6. Combine like terms:

   y^2 - 4y - 7

So, the simplified expression is y^2 - 4y - 7.
