When we combine like terms, we get:
-4x^4 + 3x^4 + 6x^4 - 3x^2 - 8x^2
Simplifying further:
-4x^4 + 9x^4 - 11x^2
Our final answer is:
5x^4 - 11x^2
Add or subtract
(3x^2 - 4x^4) - (x^2 + 3x^4) + (6x^4 - 8x^2)

I don't think so
(3x^2 - 4x^4) - (x^2 + 3x^4) + (6x^4 - 8x^2)
= 3x^2 - 4x^4 - x^2 - 3x^4 + 6x^4 - 8x^2
= -6x^2 - x^4
or
= -x^2(6 + x^2)
(3x^2 - 4x^4) - (x^2 + 3x^4) + (6x^4 - 8x^2)
= 3x^2 - 4x^4 - x^2 - 3x^4 + 6x^4 - 8x^2
= -6x^2 - x^4
or
= -x^2(6 + x^2)
