Which of the following is equal to the rational expression when x≠5 or -1?
(x-7)(x + 1)
(x + 1)(x - 5)

  (x-7)/(x-5)

The (x+1) terms divide and cancel out due to the rule that x/x = 1, when x is nonzero. In that rule, we can replace 'x' with any algebraic expression we want.

step-by-step explanation:

just plug in each number for x and see which ones work and don't
