Hi there

I'm trying to isolate (y1-3)2+(x1-1)2 in the equation 25(y1-3)2+200+100(x1-1)2=0.

I have tried isolate and solve, but solve coplains about solving for expressions (but when inputting i:=(x1,y1)->(y1-3)2+(x1-1)2 it still doesn't work), and isolate can only isolate either (y1-3)2 or (x1-1)2 . Not both.

How can I do this with as few lines as possible?

Thanks
