Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function.

f(x) = -2x4 + 4x3 + 3x2 + 18

dumbcow · Answer

Fist coefficient = 2  ----> Factors: 1,2
Last coefficient = 18 ----> Factors: 1,2,3,6,9,18

Pair each combination of factors into fractions with Last coefficient on top:
$$\rightarrow  \pm \frac{18,9,6,3,2,1}{1},\pm  \frac{18,9,6,3,2,1}{2}$$

But I was confused if I had to do more or if that was it?

dumbcow · Answer

No thats it, just make sure you reduce all the fractions and ignore any repeats
