First, you have to use Binomial Multiplication (FOIL)

#### Explanation:

That first step is crucial. Many people will just distribute the square across the expression inside the parenthesis, but that is incorrect.

So,

So,

This is a parabola that opens up. The x coordinate of the vertex of a parabola can be found by

To get the y coordinate for the vertex, plug the -2 into your equation:

So, the vertex is at (-2,0)
