I'm having trouble plotting an implicit function, in my case a circle, and a quadratic graph in power 2, on the same graph.

For example if i have the function y=x^2 + x.

and the circle: x^2 + y^2 + 12*x - 8*y = 14.

I tried a killer combo like so, but of course it plots only both graphs separately:

plot2d([implicit_plot(x^2+y^2+6*x-4*y-7=0,[x,-10, 10], [y, -10,10]),plot2d(x^2+4*x,[x,-10, 10], [y, -10,10])]);

Any help would be appreciated.

Thanks in advance
