9-125.

Now divide $x^{3} − 9x^{2} + 19x + 5$ by the factor that you chose in the preceding problem. If it is a factor, use it and the resulting factor to find all the zeros of the polynomial. If it is not a factor, reconsider your answer to the preceding problem and try a different factor.

$\text{Divide} x^{3} − 9x^{2} + 19x + 5 \text{ by } x − 5.$

$\left(x − 5\right)\left(x^{2} − 4x − 1\right)$
$x=5, 2\pm\sqrt{5}$
