The possible rational roots are the factors of the constant term divided by the factors of the coefficient of the leading term.

The constant term is 6 The leading term is x^3 and its coefficient is 1

MertsjBest ResponseYou've already chosen the best response.0
So the possible rational roots are the factors of 6 divided by the factors of 1

Let me give you an example: The factors of 12 are 4 and 3 because 4 x 3 = 12

Also 2 and 6 are factors of 12 because 2 x 6 = 12

k so which do I choose from 1 and 2?
 one year ago

gojani91Best ResponseYou've already chosen the best response.0
this is an easy problem because the leading coefficient is 1 from x^3 so all those numbers can be divided by 1

your question ask which is not a possible root number
