(X^2 + 2X +1) - Y^2 ..........Seperate the terms ,you can see the whole square.
(X+1)^2 - Y^2 ..........Now you can apply the factorisation that you already know.
(X+1+Y)(X+1-Y) ..........Easy isn't it......
I have a problem here - can anybody help?
Factorize X^{2 - }Y^{2 + }2X + 1
I think it can be: (x+Y)(x-y) +2X + 1 - but I' m not sure whether I'm correct, or can it be further factorized?
Help -- and thanks in advance!
