2. We are solving for the real number $y$ .
3. If there are multiple solutions, they should be separated by commas.
4. The solutions should be rounded to the nearest hundredth.

STEP 2

To solve for $y$ , we first need to isolate the $y^2$ term. We can start by adding 96 to both sides of the equation.
