    (z^2+8z+16/z^2-100)*(z^2-10z/z+4) = z^2*(z^2-10z/z+4)+8z*(z^2-10z/z+4)+16/z^2-100*(z^2-10z/z+4) u can finish it right?

    z^2*(z^2-10z/z+4) = z^4-10z^3/z+4 8z*(z^2-10z/z+4) = 8z^3-80z^2/z+4 16/z^2-100*(z^2-10z/z+4) = (16z^2/z^2-100)-(160z/(z^2-100)(z+4)) from this is easier

    (z^2+8z+16/z^2-100)*(z^2-10z/z+4) = z^2*(z^2-10z/z+4)+8z*(z^2-10z/z+4)+16/z^2-100*(z^2-10z/z+4) =z^4-10z^3/z+4+8z^3-80z^2/z+4+(16z^2/z^2-100)-(160z/(z^2-100)(z+4)) and you simplify by urself from this

    The problem statement seems to be: \[\frac{\left(z^2+8 z+16\right) \left(z^2-10 z\right)}{\left(z^2-100\right) (z+4)} \] Both of the products in the Numertor can be factored as well as the first product of the Denominator. Factor and then simplify. \[\frac{(4+z)^2 (-10+z) z}{(-10+z) (10+z) (z+4)}=\frac{z (4+z)}{10+z}\]
