Hi, I'm William24, a Form 2 student from Hong Kong...factorization problem here:

(Crying)

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!

(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......

Hi sohamjariwala,

Thank you so much! You're so clever!
Have a great weekend.
