8-100.

Now divide *x*^{3} – 9*x*^{2} + 19*x* + 5 by the factor that you chose in the previous problem. If it is a factor, use it and the resulting factor to determine all the roots of the polynomial. If it is not a factor, reconsider your answer to the previous problem and try a different factor. Homework Help ✎

*x*^{3} − 9*x*^{2} + 19*x* + 5 = (*x* − 5)(*x*^{2} − 4*x* − 1)

*x* − 5 = 0*x*^{2} − 4*x* − 1 = 0

Now finish solving.
