What am I doing wrong here?
(5x^2  5) / (x  1) = 5x(x  1) / (x  1) = 5x
The answer should be 5(1 + 1)

Best ResponseYou've already chosen the best response.1(5x^2  5) / (x  1) = 5(x + 1) / (x  1) ________ The underlined part is wrong. 5x^25 Take out the common factor 5 => 5 (x^2 1) Factor (x^21) using the identity \(a^2b^2 = (a+b)(ab)\) Can you try it again?
