Integral(x*E, (x, -oo, 0))
Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    exdx=exdx\int e x\, dx = e \int x\, dx

    1. The integral of xnx^{n} is xn+1n+1\frac{x^{n + 1}}{n + 1} when n1n \neq -1:

      xdx=x22\int x\, dx = \frac{x^{2}}{2}

    So, the result is: ex22\frac{e x^{2}}{2}

  2. Add the constant of integration:

    ex22+constant\frac{e x^{2}}{2}+ \mathrm{constant}


The answer is:

ex22+constant\frac{e x^{2}}{2}+ \mathrm{constant}
