There are no zeroes.

#### Explanation:

You can use the discriminant,

The equation is already in the right form of

In this situation, a = 4, b = 0, and c = 1.

When you use the discriminant, if the answer is creater than zero, there are two roots (aka zeroes); if the answer is zero, there is one root; and if the answer is smaller than zero, there are no roots.

Since the answer is -16, there are no zeroes.
