I have a parametric curve defined by the equations;(adsbygoogle = window.adsbygoogle || []).push({});

[tex]x = t^2 + \frac{2}{t}[/tex]

[tex]y = t^2 - \frac{2}{t}[/tex]

This is part of a 12 mark question, I have done all the other parts except:

(d) Verify that the Cartesian equation of the curve is [itex](x+y)(x-y)^2 = k[/itex], stating the value of k.

The previous questions involved finding the co-ordinated at a point, the gradient of the point and hence and equation for the normal at that point.

I know you have to some how isolate t, but I've never done it before when there is two terms.

Help please.
