    If you cancel with x you will lose a value, try solving it without dividing by x.

    Sorry for my terrible handwriting, but you can never divide through by a variable as you lose a solution, so you take 2X from each side then factorise out xe^x^2

    The 2x’s cancel eachover out, so we are left with 6xe^x^2=xe^x^2

    Ignore the e^x^2 as this will clearly just be the same for all x we have 6x=x. Therefore x must equal zero.


    Hope that helps.


    EDIT. seen the above post, that is correct. I didn’t account for the x^2

    not canceling x (a solution) makes logical sense. thank you.
