I can not get this answer, do you mind helping me, please and thank you!

a. Use the Product Rule to find the derivative of the given function. b. Find the derivative by expanding the product first. f(x) = (x-5)(5x+2) O A. The derivative is (x - 5)(5x +2) (_. O B. The derivative is (x - 5)(5x +2) + (_ O C. The derivative is (x - 5)( +(5x+2) ( ) O D. The derivative is ( ) (x - 5) O E. The derivative is (*(5x+2) b. Expand the product. (x - 5)(5x +2) = (Simplify your answer.) Using either approach,- dx (X - 5)(5x+ 2) =
