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) = x6 - 14x4 - 35x2 + 48; c = 4
A. Yes; f(x) = (x - 4)(x5 + 4x4 - 2x3 + 12x2 - 3x - 12) B. Yes; f(x) = (x - 4)(x5 - 5x4 + 3x3 + 8x2 - 3x - 12) C. Yes; f(x) = (x - 4)(x5 + 4x4 + 2x3 + 8x2 - 3x - 12) D. No
