Factoring Question Help?

4(x - y)^2 - (x + y)^2

How would you factor this? Would it be using difference of squares?

Thanks ^^

I would've answered his as well if it wasn't already answered. So I chose to criticize your "answer" instead of repeating what others already did.

When someone asks "how do you factor this?" and you answer "factor," do you think you're actually helping

Difference of two squares, or if you are bored:
1. distribute/foil it out: 3x^2 - 10xy + 3y^2
2. then factor: (x - 3y) (3x - y)
__a=3 b=-10y c=3y^2
__x=3y or y/3
__(x - 3y) (x - y/3) or (x - 3y) (3x - y)

Yep, difference of 2 squares
4(x - y)^2 - (x + y)^2
=(2(x-y)-(x+y))*(2(x-y)+(x+y)
=(x-3y)*(3x-y)
