sin^4 x + (2 sin^2 x) (cos^2 x) + cos^4 x = 1 for this one, first, i factored and got: sin^2 x (sin^2 x + 2) cos^2 x (1 + cos^2 x) =1 I don't know if the factoring helped or did anything, but I can't seem to get anything else to get 1.

If you rewrite the problem as maybe it is a bit clearer.
wow i did some totally unnecessary work...thanks a lot for your help!!!
sin^4 x + (2 sin^2 x) (cos^2 x) + cos^4 x = 1, (sin^2 x + cos^2 x)^2 = 1 1^2 = 1 1 = 1
