Can You Use U-Sub Instead of Integration by Parts Sometimes? | Calculus 2 | Math with Professor V

I was asked the question by a subscriber if you can use u-substitution instead of integration by parts to solve this integral...let's investigate why the answer is (spoiler alert!) NO, but make sure we understand why.
Also, I decided I'm assigning you all homework! ;) Watch until the end to see your assignment.
