$$\int\limits_{0}^{1} \frac{1}{- 4 \sqrt{x} + 3 x}\, dx$$

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

Detail solution

Let $u = \sqrt{x}$ .

Then let $du = \frac{dx}{2 \sqrt{x}}$ and substitute $2 du$ :

$\int \frac{2}{3 u - 4}\, du$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{1}{3 u - 4}\, du = 2 \int \frac{1}{3 u - 4}\, du$
  1. Let $u = 3 u - 4$ .
    
    Then let $du = 3 du$ and substitute $\frac{du}{3}$ :
    
    $\int \frac{1}{3 u}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:
      
      $\int \frac{1}{u}\, du = \frac{\int \frac{1}{u}\, du}{3}$
      1. The integral of $\frac{1}{u}$ is $\log{\left(u \right)}$ .
      So, the result is: $\frac{\log{\left(u \right)}}{3}$
    Now substitute $u$ back in:
    
    $\frac{\log{\left(3 u - 4 \right)}}{3}$
  So, the result is: $\frac{2 \log{\left(3 u - 4 \right)}}{3}$
Now substitute $u$ back in:

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

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

The answer is:

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