List the possible rational roots 2x^4-x^2-3=0

For this specific problem, the possible rational roots of 2x^4-x^2-3=0 would be ±√(3/2). I am hoping that this answer has satisfied your query about and it will be able to help you, and if you’d like, feel free to ask another question.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
