Simplify X2 - 1 divided by X - 1?

Answer 1

To simplify the expression (X^2 - 1) / (X - 1), we can first factor the numerator as a difference of squares: (X^2 - 1) = (X + 1)(X - 1). Then, we can rewrite the expression as ((X + 1)(X - 1)) / (X - 1). Next, we can cancel out the common factor of (X - 1) in the numerator and denominator, leaving us with the simplified expression of X + 1.

Answer 2

(X^2 - 1)/(x-1) = (X+1)(X-1)/(X-1) = X+1
