Question

Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function.

f(x) = -2x^4 + 4x^3 + 3x^2 + 18

Answer 1

no rational roots

Answer 2

i think the question asks for "possible rational roots"

Answer 3

factors of 18: +/-1,+/- 2, +/-3, +/-6,+/-9, +/-18
factors of -2:+/-1,+/-2
p/q:+/-1,+/-2,+/-3,+/-6,+/-9,+/-18,+/-1/2,+/-3/2,+/-6/2,+/-9/2+/-18/2
let me know if you have any more question:)
