Thread: Need Help!

I don't completely understand this.

multiply and simplify

36y^2 * 3y-12
3y^2-24y+48 6y

here is what I understand

(36y^2)(3y-12)
(3y^2-24y+48)(6y)

(36y^2)3(y-4)
3(y^2-8y+16)(6y)

what do I do next if I am correct?

You are correct so far.

Well, we can see we can cross-out the 3 on top and bottom to get



Let's try to cross-out the 6y on the bottom:





We can factor y^2-8y+16 to get (y-4)^2



We can cross out the (y-4) on the bottom and top



And that's as far as we can go.

Thank you, you explained that very well I have a full understanding now
