There are several tutorials here that explain this process. Read several of these and follow directions. If you have further trouble, be sure to post your specific question again ... when some math teachers are awake!
12y^6-40y^5+28y^4
Take out the GCF..for example, each term has at LEASt a y^4 and the highest number it each can be divided by is 4 so..
4y^4(3y^2-10y+7)
