   1. Integrate term-by-term:

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

         $$\int 4 x^{3}\, dx = 4 \int x^{3}\, dx$$

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

            $$\int x^{3}\, dx = \frac{x^{4}}{4}$$

         So, the result is: $x^{4}$

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

         $$\int \left(- 4 x\right)\, dx = - 4 \int x\, dx$$

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

            $$\int x\, dx = \frac{x^{2}}{2}$$

         So, the result is: $- 2 x^{2}$

      The result is: $x^{4} - 2 x^{2}$

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

      $$\int 2\, dx = 2 x$$

   The result is: $x^{4} - 2 x^{2} + 2 x$

2. Now simplify:

   $$x \left(x^{3} - 2 x + 2\right)$$

3. Add the constant of integration:

   $$x \left(x^{3} - 2 x + 2\right)+ \mathrm{constant}$$

The answer is:
