1. The problem statement, all variables and given/known data f(x)=24x7-13x6-19x5+7x4-7x3+5x2+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..
