Question

Use the Rational Zero Theorem to find the real solution(s). Answer exactly. x^3-4x^2+2x+4=0

Answer 1

None of them work

Explanation:

According to the theorem, the rational zeros are of the form p/q, where p is a factor of the constant term (4 in this case) and q is a factor of the leading coefficient (1 in this case).

`(P)/(q)` =
`(1,2,4)/(1)` = ± (1,2,4)

Subtitute in and none of them work.
