**Steve**, Thursday, June 14, 2012 at 12:46pmfirst notice that you can factor out the y, leaving

y(y^2-13y+36)

Now you want two numbers that add to -13 and multiply to 36. Obviously they must both be negative. Easy factors of 36 are

1,36 2,18 3,12 4,9

It's clear that we want 4 and 9, so our polynomial is

y(y-4)(y-9)

This factoring by inspection is mainly a skill acquired by doing a lot of problems, so you get to recognize likely factors.
