You cannot graph quadratics by finding its zeros: you need a lot more points.

Some quadratics will have no zeros. Having the zeros does not tell you whether the quadratic is open at the top (cup or smiley face) or open at the bottom (cap or grumpy face). Furthermore, it gives no indication as to how far above, or below, the apex is.

The zeros will only tell you where the graph crosses the x-axis (if it does at all). That will help in graphing the equation, but you will need some additional information, as well.

How do you find complex zeros on a graph?

It's actually quite hard to graph complex numbers - you would need a four-dimensional space to graph them adequately. I believe it's more convenient to find zeros analytically for such functions.
