Please help me use Factor Theorem to determine if the given binomial is a factor of the given polynomial function:
f(x) = 4x^4 - 20x^3 + 33x^2 - 22x + 5; x - 5/2

Question

Please help me use Factor Theorem to determine if the given binomial is a factor of the given polynomial function:
f(x) = 4x^4 - 20x^3 + 33x^2 - 22x + 5; x - 5/2

anonymous · Answer

(A)  f(-5/2) = 0; yes, the binomial is a factor of the polynomial
(B)  f(5/2)=0 ; yes, the binomial is a factor of the polynomial
(C)  f(-5/2) =/= 0; the binomial is not a factor of the polynomial.
(D)  f(5/2) =/= 0; the binomial is not a factor of the polynomial

anonymous · Answer

only B and D make sense, check those

anonymous · Answer

when i say "check" i mean "cheat" you are going to have to use a calculator anyways it turns out $\frac{5}{2}$ is a zero http://www.wolframalpha.com/input/?i=+4x^4+-+20x^3+%2B+33x^2+-+22x+%2B+5

So my answer is B? @satellite73
