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:

      2xdx=2xdx\int 2 x\, dx = 2 \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: x2x^{2}

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

      ((1)2)dx=2x\int \left(\left(-1\right) 2\right)\, dx = - 2 x

    The result is: x22xx^{2} - 2 x

  2. Now simplify:

    x(x2)x \left(x - 2\right)

  3. Add the constant of integration:

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


The answer is:

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