Find the derivative using the ways below. a. Using the Quotient Rule. Simplify your result. b. By simplifying the quotient first. Verify that your answer agrees with part (a). X a y= X - a. What is the immediate result of applying the Quotient Rule? O A. y'= (x - a)(2x) - (x2 -a2) (1) (x - a )2 O B. y' = (x - a)(2x) + (x2-a=) (1) O c. (x- a)(2x) + (x2 -a2) (1) x- a O D. y' = (x - a)(2x) - (x2 -a?) (1) b. Simplify the quotient. 2 X a V= x- aFind the derivative using each method. Select the correct choice below and fill in the answer box to complete your choice. O A. The derivatives are different. The derivative using the Quotient Rule is and the derivative by simplifying the quotient is (Simplify your answers.) O B. The derivatives are the same. The derivative is (Simplify your answer.)
