Question

According to the rational root theorem, which statement about f(x)= 12x^3-5x^2+6x+9 is true?

Answer 1

Any rational root of f(x) is a factor of 9 divided by a factor of 12

which is answer D

Answer 2

If there are any rational roots, it would be a factor of your constant term (9) divided by a factor of the high-order coefficient (12).
