Using synthetic division, determine whether the numbers are zeros of the polynomial function. x+7x-11x+20 -5, 2; f(x) = 2x + Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. OA. The number - 5 is not a zero of the polynomial function because f(-5)= of the polynomial function because f(2) = OB. The number - 5 is a zero of the polynomial function because f(-5)= of the polynomial function because f(2) = and the number 2 is a zero and the number 2 is not a zero
