Question

Use the Rational Zero Theorem to list all possible rational zeros for the given function.

f(x) = -2x3 + 4x2 - 2x + 8

Answer 1

So this theorem tells us that the possible zeros are all of the factors of the constant term divided by all the possible factors of the leading coefficient. This can be written like this and then simplified toyour liking:

\[\frac{ \pm 8, 4, 2, 1 }{ \pm 2, 1 }\]

You can simplify all those possible combinations and that would be your answer : )

Answer 2

Got it! thanks again :)
