Question 70840
Well you're almost there, you have the first step down. Next you need to factor the terms inside the parenthesis. First we need to find out what terms multiply to 36 and add to -12: -6 and -6 works perfectly. These are going to be the terms in our factors So we can further factor it to:
{{{y(y^2-12y+36)}}}
{{{y(y-6)(y-6)}}}Notice the -6's? If you FOIL this you get y^2-12y+36
And it could be further written as 
{{{y(y-6)^2}}}Since there are two (y-6) terms
