$$\int\limits_{0}^{1} \left(x^{2} + 1\right)^{2}\, dx$$

Integral((x^2 + 1)^2, (x, 0, 1))

Detail solution

Rewrite the integrand:

$\left(x^{2} + 1\right)^{2} = x^{4} + 2 x^{2} + 1$
Integrate term-by-term:
1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x^{4}\, dx = \frac{x^{5}}{5}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int 2 x^{2}\, dx = 2 \int x^{2}\, dx$
  1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
    
    $\int x^{2}\, dx = \frac{x^{3}}{3}$
  So, the result is: $\frac{2 x^{3}}{3}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int 1\, dx = x$
The result is: $\frac{x^{5}}{5} + \frac{2 x^{3}}{3} + x$
Add the constant of integration:

$\frac{x^{5}}{5} + \frac{2 x^{3}}{3} + x+ \mathrm{constant}$

The answer is:

$\frac{x^{5}}{5} + \frac{2 x^{3}}{3} + x+ \mathrm{constant}$
