(x^4 - 81)/(x+3)
= (x^2 + 9)(x^2 - 9)/(x+3)
= (x^2 + 9)(x+3)(x-3)/(x+3)
= (x^2 + 9)(x-3) , x ≠-3
None of your choices represent the "simplified" form, but once you expand my answer, one of them shows up.
A. x cubed minus 3 times x squared plus 9 times x minus 27
B. the quantity x squared plus 9 times the quantity x squared minus 9
C. x cubed plus 3 times x squared plus 9 times x plus 27
D. x cubed plus 3 times x squared minus 9 times x minus 27
= (x^2 + 9)(x^2 - 9)/(x+3)
= (x^2 + 9)(x+3)(x-3)/(x+3)
= (x^2 + 9)(x-3) , x ≠-3
