Use the Factor Theorem to determine whether x - c is a factor of the given function for the given value of c. If x - c is a factor, then write f in factored form. That is, write f(x) = (x - c)(quotient).f(x) = x4 + 6x3 + 8x2 + 41x - 42; c = -6

A. Yes; f(x) = (x + 6)(x3 + x - 7) B. Yes; f(x) = (x - 6)(x3 + 8x + 7) C. Yes; f(x) = (x + 6)(x3 + 8x - 7) D. No
