You should study what is presented here, very closely:
Change a quadratic equation from general form to standard form - video

You can directly read the vertex coordinates from the standard form equation. That gives information for graphing.

Observe that your given equation is equivalent to , so you should use this as your starting general-form equation.

------Actually this is for the function . The vertex occurs at .

The only realistic graph for would be TWO points on a single numberline, only if these are real numbers and not containing imaginary parts. The zeros for your equation are .

These are NOT real numbers.
