#### Answer:

The quadratic formula always gives two answers. In this case,

#### Explanation:

To find the 'zeros', you want to solve the function for when y=0:

There is a general form for this, which is what we will be using to describe the quadratic formula:

The quadratic formula looks like this:

For this case:

Now, let's plug those into the formula:

Now, we solve for both scenarios of x:
