{{{((w^2-1)/(w-1)^3)*((w-1)/(w^2+2w+1))}}} Factor the numerator of the first fraction and denominator of the second fraction.
{{{(cross((w-1))cross((w+1))/(cross((w-1))cross((w-1))(w-1)))*(cross((w-1))/(cross((w+1))(w+1)))}}} Cancel the common factors as indicated to leave you with:
{{{1/(w-1)(w+1) = highlight(1/(w^2-1))}}}
