Question

Which of the following is equal to the rational expression when x + 1 or -1? 5(x-1) (x + 1)(x-1)

Answer 1

Answer

Option A is correct.

$\frac{5}{(x+1)}$

Explanation

We can see that the numerator and the denominator both contain (x - 1).

Hence, that expression cancels out and we are left with

5/(x + 1)
