#### Explanation:

To go from Standard Form to Vertex Form, we need to *complete the square*. That means we need to find the constant that makes

To find that constant, we use this equation:

We now have the constant that completes the square, but we can't just add a value to an equation. We can either add

That's our vertex form, so now we're done. Good job!
