The zeros are
Larger
Smaller
2)The vertex is (-12.5,-2.25)
Explanation:
The given function is:

This function is already in the factored form therefore it is easy to find the zeros,

Either or
The zeros are or
b) The expanded form of the given function is:

We obtain the vertex form by completing the square:

The vertex form is:

Therefore the vertex is (-12.5,-2.25)
