I think the best we can do is

#### Explanation:

A reference to "the vertex form" implies that we are dealing with a parabolic equation; **not** a parabolic equation.

We could replace

which is a parabolic equation with the vertex at

Replacing

but as noted, this is not a parabola (see graph below)

graph{x^4-2x^2-2 [-6.783, 7.26, -4.515, 2.505]}
