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 n≠−1n \neq -1:

        ∫x2 dx=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:

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

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

          ∫x dx=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:

      ∫2 dx=2x\int 2\, dx = 2 x

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

  2. Now simplify:

    x(2x2−9x+12)6\frac{x \left(2 x^{2} - 9 x + 12\right)}{6}

  3. Add the constant of integration:

    x(2x2−9x+12)6+constant\frac{x \left(2 x^{2} - 9 x + 12\right)}{6}+ \mathrm{constant}

The answer is:

x(2x2−9x+12)6+constant\frac{x \left(2 x^{2} - 9 x + 12\right)}{6}+ \mathrm{constant}
