Find the error in the following work. d 2x+5 2 dx x². - 1 (2x+5)(2x)-(x²-1)2 (x²-1)² 4x²+10x-2x²+2 2 (x²-1)2 2x²+10x+2 (x²-1)² Choose the correct answer. ○ A. In the first step, the numerator should be (x² - 1) (2x+5)-(2x)2. OB. In the first step, the numerator should be (x²-1) 2-(2x+5)(2x). OC. In the last step, the numerator should be 2x² - 10x+2. OD. In all three steps, the denominator should be (2x+5)².
