simple algebra given, (x^2 + y^2 - 4x)^2 = 2(x^2 + y^2) and x = 1, what are the possible values for y?
the graph of that function is http://www.webassign.net/waplots/4/4/655c462cd57377b2a426a69f2b79a0.gif and i 'm finding the coordinate of P where x=1 and y is -??

na i got it, is + or - 1 and + or - sqrt 7
it was an implicit differential to find the tangent but i got it cuz i wasnt usin calculator lol
