Using synthetic division, determine whether the numbers are zeros of the polynomial function. -5, 4; f(x) = 2x3 + 5x2 - 19x + 30
Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.
O A. The number - 5 is a zero of the polynomial function because f(-5) = and the number 4 is not a zero of the polynomial function because f(4) =
OB. Neither - 5 nor 4 is a zero of the polynomial function because f(-5) = and f(4)=
O c. The number - 5 is not a zero of the polynomial function because f(-5)= and the number 4 is a zero of the polynomial function because f(4) =
O D. Both -5 and 4 are zeros of the polynomial function because f(-5) = 0 and f(4)=0.
