Answer 3

To simplify the expression (1 + y) - y(y + 3)(y - 3), you can start by expanding the terms and then combining like terms. Here's the step-by-step simplification:

1. Distribute y into the second term, y(y + 3)(y - 3):

   y(y + 3)(y - 3) = y(y^2 - 9) (Use the FOIL method for the binomial)

   y(y^2 - 9) = y^3 - 9y

2. Now, the expression becomes:

   (1 + y) - (y^3 - 9y)

3. Distribute the negative sign into the second term:

   (1 + y) - y^3 + 9y

4. Now, combine like terms:

   (1 - y^3) + (y + 9y) = 1 - y^3 + 10y

So, the simplified expression is 1 - y^3 + 10y.
