Find the error in the following work . D X ] 2 x + 5} X 2 - 1 ( 2 x + 5 ) ( 2 X ) - ( X 2 - 1) 2 ( X 2 - 1 ) 2\\ = 4 X 2 + 10 * - 2 X 2 + 2\\ ( X 2 - 1 ) 21 = 2 X 2 + 10 * + 2 ( * 2 - 1 ) 2 Choose the correct answer below . O A . In the last step , the numerator should be 2 x 2 - 10 * + 2 . OB . In the first step , the numerator should be ( * 2 - 1 ) 2 - ( 2X + 5 ) ( 2 X) . O C . In all three steps , the denominator should be ( 2 x + 5 7 2 . O D. In the first step , the numerator should be ( * 2 - 1 ) ( 2 x +5 ) - ( 2 X ) 2
