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:

        4xdx=4xdx\int 4 x\, dx = 4 \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: 2x22 x^{2}

      The result is: x33+2x2\frac{x^{3}}{3} + 2 x^{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+2x25x\frac{x^{3}}{3} + 2 x^{2} - 5 x

  2. Now simplify:

    x(x2+6x15)3\frac{x \left(x^{2} + 6 x - 15\right)}{3}

  3. Add the constant of integration:

    x(x2+6x15)3+constant\frac{x \left(x^{2} + 6 x - 15\right)}{3}+ \mathrm{constant}


The answer is:

x(x2+6x15)3+constant\frac{x \left(x^{2} + 6 x - 15\right)}{3}+ \mathrm{constant}
