Derivative using product rule

In this math example, we use the product rule to find the derivative of a given function that is defined to be a polynomial multiplied by a function containing an exponential (e^x). To do so, we 1st map out a plan for what is required for the product rule f'*g+.f*g' Then we fill in to each piece of the plan by taking the derivatives one term at a time by both using the power rule and the derivative of e^x.
