To solve this question you must FOIL (First, Outside, Inside, Last) like so
First:
(x^2 + 4)(x^2 - 4)
x^2 * x^2
x^4
Outside:
(x^2 + 4)(x^2 - 4)
x^2 * -4
-4x^2
Inside:
(x^2 + 4)(x^2 - 4)
4 * x^2
4x^2
Last:
(x^2 + 4)(x^2 - 4)
4 * -4
-16
Now combine all the products of the FOIL together like so...
x^4 - 4x^2 +4x^2 - 16
Combine like terms:
x^4 - 4x^2 +4x^2 - 16
- 4x^2 +4x^2 = 0
x^4 - 16 <<<This is your answer
Hope this helped!

We have the expressions:
Now, with this we operate as follows:
a)
Then, the axis is x = -3 and the vertex (-3, 6)
b)
Then, the vertex is (2, 5) and the axis is x = 2.
c)
Then, the vertex is (2, -4) andd the axis is x = 2.
d)
Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
