(0,0), (6,6), and (-6,6)?

**Steve**, Friday, May 17, 2013 at 10:30amHmmm.

y = -x^2 so

x^2 - (-x^2-6)^2 = 36

x^2 - x^4 - 12x^2 - 36 = 36

x^4 + 11x^2 + 72 = 0

I don't see any real solutions. 11^2-4*72 < 0

**Steve**, Friday, May 17, 2013 at 10:49amAnd yet, I do see that your points work.

Hmmm.

**Steve**, Friday, May 17, 2013 at 10:53amNo, they don't they fit the first equation, but not the 2nd.

Only (0,0) works in both

**Steve**, Friday, May 17, 2013 at 10:55amNope. (0,0) does not work in the 1st.

0 - 36 ≠ 36

Can't believe I let you fool me! :-)
