Detail solution

  1. Integrate term-by-term:

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

      ∫3x2 dx=3∫x2 dx\int 3 x^{2}\, dx = 3 \int x^{2}\, dx

      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}

      So, the result is: x3x^{3}

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

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

    The result is: x3−3xx^{3} - 3 x

  2. Now simplify:

    x(x2−3)x \left(x^{2} - 3\right)

  3. Add the constant of integration:

    x(x2−3)+constantx \left(x^{2} - 3\right)+ \mathrm{constant}

The answer is:

x(x2−3)+constantx \left(x^{2} - 3\right)+ \mathrm{constant}
