so do you know anything about the rrt?
OpenStudy (anonymous):
No , sadly . . . :(
OpenStudy (anonymous):
its cool, its not hard you take the leading exponential's(x^3) coefficient and the constant (3) and arrange them like so 3/1, 1/1, -1/1, -3/1 So that would be all the numbers that they are divisible by, plus their negatives.
OpenStudy (anonymous):
and always the constant over the leading coefficient.
OpenStudy (anonymous):
so are they always gonna be over 1 ? like /1 ?

not always. if it had been 3x^3 - x^2 - x - 3 = 0 then you would have 3/3; 3/1; 1/3; 1/1 and etc
OpenStudy (anonymous):
