Iwant to know if i'm on the right path or not, the answer i got was 2157; am i right or wrong, if not can someone me? ?

find each f(c) using synthetic substitution.
f(x) =5x^5+ 10x^4+ 3x^3+ 8x^2– 6x – 3; c = 3

  f(3) = 2157

Step-by-step explanation:

Finding the remainder using synthetic division is essentially equivalent to evaluating the following using x=3:

  f(x) = 5x +10)x +3)x +8)x -6)x -3

  f(3) = 5·3 +10)3 +3)3 +8)3 -6)3 -3

  = (((25·3 +3)3 +8)3 -6)3 -3

  = ((78·3 +8)3 -6)3 -3

  = (242·3 -6)3 -3

  = 720·3 -3

  = 2157

Your answer looks right to me.
