If x > 7, which of the following is equal to (x^2 + 2x + 1)/(x^2 - 1) ?
If x > 7, which of the following is equal to (x^2 + 2x + 1)/(x^2 - 1) ?
Answer/Solution
(x + 1)/(x - 1)
Steps/Work
(x^2 + 2x + 1)/(x^2 - 1)
= (x + 1)(x + 1) / (x + 1)(x - 1)
=(x + 1)/(x - 1)
D. (x + 1)/(x - 1)
= (x + 1)(x + 1) / (x + 1)(x - 1)
=(x + 1)/(x - 1)
D. (x + 1)/(x - 1)
