Use synthetic division and the Remainder Theorem to find the indicated function value.

f(x) = x5 - 8x4 - 9x3 - 6; f(3)


I keep coming up with the answer of -222, but that is not an option... I don't know what I'm doing wrong!!! PLEASE HELP--I only have 20 mins left to submit this...
Thanks

    I don't understand why you have to use synthetic division and the remainder theorem to compute the value of the function at x=3.
    The answer is 2^5 -8*16 -9*8 -6 =-174
