Question

What are the possible rational zeroes of this function?
f(x) = 3x3 – x2 + 15x + 5

Answer 1

±1, ±2, ±5

Answer 2

±1, ±5, 1/3 , ± 2/3

Answer 3

±1, ±5, 1/3 , ± 5/3

Answer 4

±1, ±3, 1/5 , ± 3/5

Answer 5

±1, ±2, 1/3 , ± 2/3

Answer 6

use the rational roots theorem
multiply first coefficient by the last:-
3*5 = 15

so possible roots are +/1 1, +/- 3, +/- 5

Answer 7

is that a 1/3 and 3/5

Answer 8

no 3 or -3, 5 or -5, 1 or -1

of course it might not be any of these These are possibilities only.

Answer 9

\[\ \frac{ (5x – 16)}{ (x – 2)(x – 4)} \]
