You can put this solution on YOUR website! Not sure why you want to complete the square to find the inverse.

You won't find a closed form solution for this inverse.
Typically you interchange the x and y variables and solve for y.
The new y is the inverse.
So then it would be,
But isolating y in this equation is not possible.
You'd have to use numerical methods to get a handle on the inverse.
Here's a graph of the original function and the inverse.
