Question 3 of 25 Which of the following is equal to the rational expression when x!=-1 or -7 ((x+1)(x-1))/((x+7)(x+1))

Answer 1

To simplify the given rational expression, cancel out the common factors in the numerator and denominator. The expression ((x+1)(x-1))/((x+7)(x+1)) simplifies to (x-1)/(x+7).

To simplify the given rational expression, we can cancel out the common factors in the numerator and the denominator.

The expression ((x+1)(x-1))/((x+7)(x+1)) has a common factor of (x+1) in both the numerator and denominator. Canceling out this common factor, we get (x-1)/(x+7).
