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 - 12x4 - 69x2 + 80; c = 4
A. Yes; f(x) = (x - 4)(x5 - 5x4 + 5x3 + 16x2 - 5x - 20) B. Yes; f(x) = (x - 4)(x5 + 4x4 - 4x3 + 20x2 - 5x - 20) C. No D. Yes; f(x) = (x - 4)(x5 + 4x4 + 4x3 + 16x2 - 5x - 20)
