If you're only allowed to use integers, this is a prime polynomial.
If you're allowed to use complex numbers, it factors into
(x-3-2i)(x-3+2i)

as the one above said, it is not easy to factor it
find the roots.
(6 +or- sqrt(36 - 4*13) / 2
since 36 - 4*13 is a negative number and has no square root, x squared - 6x +13 has no root.
so it can't be factored

it cant be factored easily because 13 is prime.. use the quadratic equation to find the roots.

you can either factorise this equation by using the perfect square technique or the quadratic equation -> [-b+-(b^2-4ac)1/2]/(2a). i think you should know what is the a, b and c.
