Hi,

The graph has four real number solutions for values of .

I can draw the graph using my math tools, but this is quite a stinker to try and graph by hand.

I was wondering how you would find the four real solutions for a particular value of y, say 5. I have tried factoring it.

There doesn't appear to be any way of factoring out the four real number solutions. What is the correct way to find values of the graph.

Thanks

Regards

Craig.
