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) = 6x3 + 55x2 + 61x + 40; c = -8
A. Yes; f(x) = (x - 8)(6x2 + 7x - 5) B. Yes; f(x) = (x + 8)(6x2 + x + 5) C. Yes; f(x) = (x + 8)(6x2 + 7x + 5) D. No
