$$\int\limits_{0}^{1} 1 \cdot \frac{1}{5 x^{2} - 6}\, dx$$

Integral(1/(5*x^2 - 1*6), (x, 0, 1))

Detail solution

Rewrite the integrand:

$1 \cdot \frac{1}{5 x^{2} - 6} = \frac{\sqrt{30}}{60} \left(- \frac{1}{x + \frac{\sqrt{30}}{5}} + \frac{1}{x - \frac{\sqrt{30}}{5}}\right)$
The integral of a constant times a function is the constant times the integral of the function:

$\int \frac{\sqrt{30}}{60} \left(- \frac{1}{x + \frac{\sqrt{30}}{5}} + \frac{1}{x - \frac{\sqrt{30}}{5}}\right)\, dx = \frac{\sqrt{30} \int \left(- \frac{1}{x + \frac{\sqrt{30}}{5}} + \frac{1}{x - \frac{\sqrt{30}}{5}}\right)\, dx}{60}$
1. Integrate term-by-term:
  1. The integral of $\frac{1}{x - \frac{\sqrt{30}}{5}}$ is $\log{\left(x - \frac{\sqrt{30}}{5} \right)}$ .
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \left(- \frac{1}{x + \frac{\sqrt{30}}{5}}\right)\, dx = - \int \frac{1}{x + \frac{\sqrt{30}}{5}}\, dx$
    1. The integral of $\frac{1}{x + \frac{\sqrt{30}}{5}}$ is $\log{\left(x + \frac{\sqrt{30}}{5} \right)}$ .
    So, the result is: $- \log{\left(x + \frac{\sqrt{30}}{5} \right)}$
  The result is: $\log{\left(x - \frac{\sqrt{30}}{5} \right)} - \log{\left(x + \frac{\sqrt{30}}{5} \right)}$
So, the result is: $\frac{\sqrt{30} \left(\log{\left(x - \frac{\sqrt{30}}{5} \right)} - \log{\left(x + \frac{\sqrt{30}}{5} \right)}\right)}{60}$
Add the constant of integration:

$\frac{\sqrt{30} \left(\log{\left(x - \frac{\sqrt{30}}{5} \right)} - \log{\left(x + \frac{\sqrt{30}}{5} \right)}\right)}{60}+ \mathrm{constant}$

The answer is:

$\frac{\sqrt{30} \left(\log{\left(x - \frac{\sqrt{30}}{5} \right)} - \log{\left(x + \frac{\sqrt{30}}{5} \right)}\right)}{60}+ \mathrm{constant}$
