No solution?

**Steve**, Saturday, May 18, 2013 at 11:51amsecond verse, same as the first:

y = -x^2, so

x^2 - (-x^2 - 12)^2 = 144

x^2 - x^4 - 24x^2 - 144 = 144

x^4 + 23x^2 + 288 = 0

again, the discriminant is negative, so there are no solutions.

x=0 works only in the 2nd equation

(±12,12) only works in the first equation
