Use the remainder theorem to:
find the remainder when f(x) is divided by x – c, and
determine whether x – c is a factor of f(x).
f(x) = x^4  8x^3 + 9x^2  69x + 24 ;
x  8
Please show all of your work.

when f(x) is divided by x8, the remainder will be
f(8).
so f(8) = 4096  4096 + 512  552 + 24 = 16
so x8 is not a factor, or else f(8) would have been zero.
