(x + 1) / (x - 5) - (x - 2) / (x + 3) =
(x + 1) / (x - 5) * (x + 3)/(x + 3) - (x - 2) / (x + 3) * (x - 5)/ (x - 5) =
(x + 1)(x + 3) / (x - 5)(x + 3) - (x - 2)(x - 5) / (x + 3)(x - 5) =
x^2 + 4x + 3 / (x - 5)(x + 3) - x^2 - 7x + 10 / (x + 3)(x - 5) =
(x^2 + 4x + 3 - x^2 + 7x - 10) / (x + 3)(x - 5) =
11x - 7 / (x + 3)(x - 5) <===ur answer is C
