y^2= 1- 2x^2(adsbygoogle = window.adsbygoogle || []).push({});

im supposed to put it in x^2/a^2 + y^2/b^2 = 1 to find the foci and so forth.

when i try to set it up i get 2x^2 + y^2 = 1. im not sure where to go from here. if i multiply or divide to set the problem up properly the 1 will change and my equation will be messed up. can someone show me what my next step is?
