$$\int\limits_{0}^{1} \sqrt{2 x - 3}\, dx$$

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

Detail solution

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:

$\frac{\left(2 x - 3\right)^{\frac{3}{2}}}{3}$
Now simplify:

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

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

The answer is:

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