Use the Factor Theorem to determine whether x - c is a factor of f. If it is, write f in factored form, that is, write f in the form 
f(x) = 5x4 - 7x3 + 17x2 - 21x + 6; c = 1
A. Yes; f(x) = (x - 1)(5x3 + 3x2 + 15x - 6) B. Yes; f(x) = (x - 1)(5x3 - 2x2 - 16x - 6) C. No D. Yes; f(x) = (x - 1)(5x3 - 2x2 + 15x - 6)
