(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f(x)=24x^{7}-13x^{6}-19x^{5}+7x^{4}-7x^{3}+5x^{2}+72x-54

Find all the roots..

2. Relevant equations

+-(p/q)...for rational roots

3. The attempt at a solution

i tried factor theorem,, and synthetic division for the possible roots..i've used uppe/lower bounds but i can't get a single root..

when i used a software to solve for this,, the roots i got are 6 imaginaries and .77547

i have no idea how to show the solution... how to solve for imaginary roots of such irreducible polynomial function??

thX.. really need this asap..
