SOLUTION: {{{x^2 + 5x + 9 = 0}}}. Find the products of roots.

In any polynomial of even degree the product of the roots
is always the constant term divided by the coefficient of
the largest exponent of the variable. (For odd-degree
polynomials it's the same, but with the sign changed).

The constant term is  and the coefficient of the
largest exponent, , is , so the product of the roots 
is  or
