Question

Which of the following represents the set of possible rational roots for thepolynomial shown below?2x3 + 5x2 - 8x - 20 = 0oa{=}, +2, +1, +2, +3, +3 + 1}O B. {+1, +2, +4, +5, +10, 20}O a {, +1, +2 +3 +4, + 3, +10, +20)02 (1.1,2,3,4,5,10,20)

Answer 1

We will have that the set of rational roots for the expression will be:

`\mleft\lbrace\pm(1)/(2),\pm1,\pm2,\pm(5)/(2),\pm4,\pm5,\pm10,\pm20\mright\rbrace`

[Option C].
