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

(5x^2 - 5) / (x - 1) = 5(x + 1) / (x - 1) ________ The underlined part is wrong. 5x^2-5 Take out the common factor 5 => 5 (x^2 -1) Factor (x^2-1) using the identity \(a^2-b^2 = (a+b)(a-b)\) Can you try it again?
