I have no idea how to do this could you please provide the steps to solving?
use the rational root theorem to list the possible roots and actual roots
x^4-2x^3-4x^2+11x-6
p ia an interger factor of the constant term
q is an interger factor of the leading coefficient
so p is 6 and q is 1
so now factor out 6 and 1
Factors of 6 are
so
so your possible roots are
Now use syntheic division aand try out your roots.
1 and 2 works out nicely
