MATLAB: I need to fix the error I have in the script below

please help if possible i tried to fix myself but, im not experinced with the app

Recall the Chain Rule for derivatives: ( fg(x)))-f(g(x))g (x) Substitution is nothing more than rewriting this rule in Integral form by letting u g(x (g(x)) g'(x) dx - f(u) du =f(u) + C = f (g(x)) + C Note that, if u gx), then du -g (x)niferential notation, so dx - du g(x) Use this idea and the strategy outlined in the Solution Template to evaluate 3 2 - Then use int to evaluate the integral directly to compare answers.
