anonymous · Answer

so do you know anything about the rrt?

anonymous · Answer

No , sadly . . . :(

anonymous · Answer

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.

anonymous · Answer

and always the constant over the leading coefficient.

anonymous · Answer

so are they always gonna be over 1 ? like /1 ?

anonymous · Answer

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

ohh , i see now . thanks for helping me . .(:
