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:

        ∫x3 dx=x44\int x^{3}\, dx = \frac{x^{4}}{4}

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

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

      The result is: x44−x2\frac{x^{4}}{4} - x^{2}

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

      ∫5 dx=5x\int 5\, dx = 5 x

    The result is: x44−x2+5x\frac{x^{4}}{4} - x^{2} + 5 x

  2. Now simplify:

    x(x3−4x+20)4\frac{x \left(x^{3} - 4 x + 20\right)}{4}

  3. Add the constant of integration:

    x(x3−4x+20)4+constant\frac{x \left(x^{3} - 4 x + 20\right)}{4}+ \mathrm{constant}

The answer is:

x(x3−4x+20)4+constant\frac{x \left(x^{3} - 4 x + 20\right)}{4}+ \mathrm{constant}
