    Let u and v be two functions. we need to find the integral of \[\int uv \] let u be a function which is easily integrable so, the integration of uv is \[\int uv= v\int u-\int (dv \int u)\] where dv is the derivative of v. Do you understand till here?

    e^x is easily integrable, so it'll be u v= x^2 you will have to use this formula twice:)
