so far (x-4)sqrt2 and (x+4)

anonymous · Answer

(x^2 - 8x +16)(x+4)
x^3 + 4x^2 - 8x^2 -32x + 16x + 64
x^3 - 4x^2 - 16x + 64
dont really know what you wanted soz i just expanded it brus

Thanks for the answer but this are the choices

a) x$$x ^{3}-7x ^{2}-8x+16$$
b) $$X ^{3}+8x ^{2}+8x-16$$
c) $$x ^{3}+7x ^{2}+8x-16$$
D) $$x ^{3}-7x ^{2}+8x+16$$

anonymous · Answer

start with $(x+4)^2(x-1)$ and multiply out

anonymous · Answer

guess what? it is C!
it is always C

thanks
