(9x^4 - 9x^3 + 4x^2 - 9) - (3x^3 - 7x^2 + 3x^4 - 5)
Combine like terms, starting with the highest power:
9x^4 - (3x^4) = 6x^4
-9x^3 - (3x^3) = - 12x^3
4x^2 - (-7x^2) = 11x^2
-9 - (-5) = - 4
Final answer = 6x^4 - 12x^3 + 11x^2 - 4
(Remember to distribute the negative sign across the parenthesis)
Good luck in your studies.
BTW... I'm not sure how Tira got 12 for the last term.

(9x^4 - 9x^3 + 4x^2 - 9) - (3x^3 - 7x^2 + 3x^4 - 5)
= 9x^4 - 9x^3 + 4x^2 - 9 - 3x^3 + 7x^2 - 3x^4 + 5
= 9x^4 -12x^3 - 11x^2 -4
