Use the Rational Zero Theorem to list all possible rational zeros for the given function. f(x) = -2x3 + 4x2 - 2x + 8
Scorpion4ik [409]
Rational zero theorem is all combinations of p(factors of the constant) divided by q(factors of the first coefficient) 

factors of 8 are 1, 2, 4, 8
factors of 2 are 1, 2

so all possible rational zeros are all combinations of p/q

+/-   1/1, 1/2, 2/1, 2/2, 4/1, 4/2, 8/1, 8/2

Now there are some repeats in there so you have to leave those out and once we do that we get 

+/- 1, 1/2, 2, 4, 8 

Remember all those are plus OR minus

WILL GIVE BRAINLIEST *NO LINKS*
77julia77 [94]

Answer:

2 out of 5

Step-by-step explanation:

I believe that 96/240 needs to be simplified until it cant anymore, an that is the probability because they both fit three, I will divide by three.

96/3=32

240/3= 80

<u>32/80</u>

  2

16/40 then because they both fit four, Ill do four.

4/10then 2 again

2/5 so, it is 2 out of five

please correct me if I am wrong, I was never good at probabilities, but I am better now.
