$$\int\limits_{1}^{4} \left(2 x - \frac{1}{2 \sqrt{x}}\right)\, dx$$

Integral(2*x - 1/(2*sqrt(x)), (x, 1, 4))

Detail solution

Integrate term-by-term:
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int 2 x\, dx = 2 \int x\, dx$
  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: $x^{2}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \left(- \frac{1}{2 \sqrt{x}}\right)\, dx = - \int \frac{1}{2 \sqrt{x}}\, dx$
  1. Don't know the steps in finding this integral.
    
    But the integral is
    
    $\sqrt{x}$
  So, the result is: $- \sqrt{x}$
The result is: $- \sqrt{x} + x^{2}$
Add the constant of integration:

$- \sqrt{x} + x^{2}+ \mathrm{constant}$

The answer is:

$- \sqrt{x} + x^{2}+ \mathrm{constant}$
