State mistakes then correct first line. Then continue solution and find final expression for derivative, factor and simplify, no negatives in answer

Question 9 (4 points) Listen A student was asked to find the derivative of a complicated function. The function had the form f (x) y # g(x) They re-wrote the function to use the product rule and realized they needed to use the chain rule for the derivatives of f(x) and g(x). Here is the first line of their solution. y' - 5(1 + 2x)(2) (3x2 -5) 2 + (1 + 2x)5( 2)(3x2 -5) '(6 X State the mistake(s) they have made then correct the first line of the solution. Then continue the solution to find the final expression for the derivative (it should be fully factored and simplified and contain no negative exponents)
