Detail solution
  1. Integrate term-by-term:

    1. Integrate term-by-term:

      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}

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

        3xdx=3xdx\int 3 x\, dx = 3 \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: 3x22\frac{3 x^{2}}{2}

      The result is: x33+3x22\frac{x^{3}}{3} + \frac{3 x^{2}}{2}

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

      (5)dx=5x\int \left(-5\right)\, dx = - 5 x

    The result is: x33+3x225x\frac{x^{3}}{3} + \frac{3 x^{2}}{2} - 5 x

  2. Now simplify:

    x(2x2+9x30)6\frac{x \left(2 x^{2} + 9 x - 30\right)}{6}

  3. Add the constant of integration:

    x(2x2+9x30)6+constant\frac{x \left(2 x^{2} + 9 x - 30\right)}{6}+ \mathrm{constant}


The answer is:

x(2x2+9x30)6+constant\frac{x \left(2 x^{2} + 9 x - 30\right)}{6}+ \mathrm{constant}
