If x = 7 and x = 2 are simple (multiplicity 1) roots of p (x) and x = -1 is a double root , and p (1) = 48, which of the following is the complete factored form of the p (x) where p (x) is 4^th degree?

A.

B.

p(x) = 2(x - 7)(x - 2)(x + 1)²

p(x) = 4(x - 7)(x - 2)(x + 1)

p(x) = (x + 7)(x + 2)(x + 1)

None of the above
