Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have been working on this problem for a while now and can't seem to get it into a forum which would isolate x, which would then allow me to sub y and find the inverse.

The problem is x^3/x^2+1

Can anyone help me with this? I am utterly stuck

I have dealt with a similar problem before.... x+1/x-1.... the trick for that was to express the statement twice, once with x-1 in the numerator and x+2 in the numerator..... which would cancel the first statement and isolate x etc.

However, this problem we have a cube and a square in the numerator and the denomator.

Can someone please help?

Thanks
