I have an question about solving equation.

x and y are variable, and a, b, and c are complex constant.

The equations is formed like  : x^2/a - y^2/b = c.

I want to contour plot a graph range from x1 < Re(x) < x2 to y1 < Re(y) < y2. x1, x2, y1, and y2 is real number even though x and y satisfied this equation are complex number.

I have used ContourPlot[x^2/a - y^2/b == c, {x, x1, x2}, {y, y1, y2}]. However, because this considers only real case, I can't find a solution.

If anyone has a idea, please help me.

Thank you.
