    f(x)=e^x(x^2+2) f'(x)=e^x(2x)+e^x(x^2+2) f'(x)=e^x(2x+x^2+2)

    yes.... i don't know why you factored the x there but that doesn't matter I guess...

    no, it's fine. just a product rule (recalling the facts that d/dx(e^x)=e^x=integral e^x dx), all you really had to know is that the derivative of x^2+2 is 2x.
