There are no zeroes.

Explanation:

You can use the discriminant, b2−4ac .
The equation is already in the right form of y=ax2+bx+c .
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.
