A. Yes B. No
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) = x6 - 13x4 - 52x2 + 64; c = 4
A. Yes; f(x) = (x - 4)(x5 + 4x4 - 3x3 + 16x2 - 4x - 16) B. Yes; f(x) = (x - 4)(x5 + 4x4 + 3x3 + 12x2 - 4x - 16) C. Yes; f(x) = (x - 4)(x5 - 5x4 + 4x3 + 12x2 - 4x - 16) D. No
