    1. Integrate term-by-term:

      1. The integral of a constant times a function is the constant times the integral of the function:

        (x2)dx=x2dx\int \left(- x^{2}\right)\, dx = - \int x^{2}\, dx

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

          x2dx=x33\int x^{2}\, dx = \frac{x^{3}}{3}

        So, the result is: x33- \frac{x^{3}}{3}

      1. The integral of a constant times a function is the constant times the integral of the function:

        2xdx=2xdx\int 2 x\, dx = 2 \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: x2x^{2}

      The result is: x33+x2- \frac{x^{3}}{3} + x^{2}

    1. The integral of a constant is the constant times the variable of integration:

      (3)dx=3x\int \left(-3\right)\, dx = - 3 x

    The result is: x33+x23x- \frac{x^{3}}{3} + x^{2} - 3 x

  2. Now simplify:

    x(x2+3x9)3\frac{x \left(- x^{2} + 3 x - 9\right)}{3}

  3. Add the constant of integration:

    x(x2+3x9)3+constant\frac{x \left(- x^{2} + 3 x - 9\right)}{3}+ \mathrm{constant}


The answer is:

x(x2+3x9)3+constant\frac{x \left(- x^{2} + 3 x - 9\right)}{3}+ \mathrm{constant}
