Find all real roots and their multiplicity of the polynomial
The polynomial f(x) has root x=1 with multiplicity 2.
2x+5=0 if x=-5/2; Consequently f(x) has the root x=-5/2, with multiplicity 3.
The polynomial is irreducible; here is its graph again:
Finally, the term , when . Thus f(x) has the root , with multiplicity 4.
