    Question integration by parts

    i am having problems solving:

    integral of exp(x^2)*4x with respect to x

    i am using u = 4x and dv/dx = exp(x^2)

    but keep going round and round without getting a decent answer.

    where am i going wrong?

    use u= x^2 \quad \Rightarrow du = 2x \cdot dx
