$$\int\limits_{0}^{1} \left(\sqrt{2 x - 3} + \frac{1}{x + 4}\right)\, dx$$

Integral(1/(x + 4) + sqrt(2*x - 3), (x, 0, 1))

Detail solution

Integrate term-by-term:
1. Let $u = 2 x - 3$ .
  
  Then let $du = 2 dx$ and substitute $\frac{du}{2}$ :
  
  $\int \frac{\sqrt{u}}{2}\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \sqrt{u}\, du = \frac{\int \sqrt{u}\, du}{2}$
    1. The integral of $u^{n}$ is $\frac{u^{n + 1}}{n + 1}$ when $n \neq -1$ :
      
      $\int \sqrt{u}\, du = \frac{2 u^{\frac{3}{2}}}{3}$
    So, the result is: $\frac{u^{\frac{3}{2}}}{3}$
  Now substitute $u$ back in:
  
  $\frac{\left(2 x - 3\right)^{\frac{3}{2}}}{3}$
1. Let $u = x + 4$ .
  
  Then let $du = dx$ and substitute $du$ :
  
  $\int \frac{1}{u}\, du$
  1. The integral of $\frac{1}{u}$ is $\log{\left(u \right)}$ .
  Now substitute $u$ back in:
  
  $\log{\left(x + 4 \right)}$
The result is: $\frac{\left(2 x - 3\right)^{\frac{3}{2}}}{3} + \log{\left(x + 4 \right)}$
Now simplify:

$\frac{\left(2 x - 3\right)^{\frac{3}{2}}}{3} + \log{\left(x + 4 \right)}$
Add the constant of integration:

$\frac{\left(2 x - 3\right)^{\frac{3}{2}}}{3} + \log{\left(x + 4 \right)}+ \mathrm{constant}$

The answer is:

$\frac{\left(2 x - 3\right)^{\frac{3}{2}}}{3} + \log{\left(x + 4 \right)}+ \mathrm{constant}$

$$\int \left(\sqrt{2 x - 3} + \frac{1}{x + 4}\right)\, dx = C + \frac{\left(2 x - 3\right)^{\frac{3}{2}}}{3} + \log{\left(x + 4 \right)}$$
