i'm trying to understand one thing ..

anonymous · Answer

I'm sorry -- what do you need help with?

anonymous · Answer

i wanted to knw how you got rid of the y^3

anonymous · Answer

I didn't get rid of it, I just factored it out of the equation. When you have variables across an entire function (the equation you posted is a function), you can pull them out and multiply it by the entire function, like this:

anonymous · Answer

$$y^2(4 + 3y - 6 +6y)$$

anonymous · Answer

Oops, that should be 4 - 3y, not 4 + 3y at the beginning. Still though, the principle is the same.

anonymous · Answer

oh, okay. thank you !

anonymous · Answer

If you multiply that $$y ^{2}$$ across everything in the parentheses you'll get what you started with. And that's how you factor. Just like how 2 x 2 x 2 = 8. You can do this: 2(2 x 2) = 8

You're welcome. Sorry about the confusion.
