    When you differentiate e^x^2, there's no need to multiply by another x^2.

    I did it for you - check your post

    I recommend using imgur to upload images then post the link (including the file type e.g. ,jpg) inside [img] tags.

    Using the product rule y=xe^x2
    Let u= x and v= e^x2. Therefore, u'= 1 and v'= 2xe^x2

    So using the product rule dy/dx= u.v' + v.u'
    This mean dy/dx= (x) . (2xe^x2) + (e^x2) . (1)
    This is equal to 2x2e^x2 + e^x2
    Factorising this produces e^x2(2x2 + 1), hope this helps simplify it a little.
