You don't have to go that far. Try proving that this factors over integers completely by applying rational root theorem (integral root theorem for monic polynomials).wishmaster said:I know how to find the roots with Horners method
The polynomial has degree 3, so that it exists at least one real root that can be found with the Newton-Raphson method...I have given polynomial: \(\displaystyle x^3-8x^2+19x-12\)
I know how to find the roots with Horners method,i am just wondering if there is an easier and quicker way to find them? Thank you!
I will try it,but i cant see that this method can be shorter......again you have to test it it with Horners method. Or can you show me how to do it with my example?
