Textbook Problem

Name two major errors in the following graded test question, and give the correct answer. d d x [ ( 3 x 3 − x ) ( 2 x + 1 ) ] 4 = 4 [ ( 9 x 2 − 1 ) ( 2 ) 3 ] X WRONG SEE ME!

To determine

The major errors and correct answer for the given solution ddx[(3x3x)(2x+1)]4=4[(9x21)(2)]3.

Explanation

Given Information:

Function with wrong derivative is ddx[(3x3x)(2x+1)]4=4[(9x21)(2)]3.

Consider the function, ddx[(3x3x)(2x+1)]4

Apply the chain rule,

ddx[(3x3x)(2x+1)]4=4[(3x3x)(2x+1)]3ddx[(3x3x)(2x+1)]=4[(3x3x)(2x+1)]3[(3x3
