Find all the roots of the equation f(x) = 6x^5-13x^4+27x^3+22x^2-78x+36=0
It suggests using Rational Root Theorem, Descartes rule, and such. I only managed to find two roots...they are 1 and 2/3. I'm left with 6x^3-3x^2+18x+54=0 as the quotient...and when I try to continue trial and error with synthetic division, I can't find the other roots. Help please!
Thank you.
