$$\int\limits_{d}^{1} d y \left(x^{2} + 3 x y\right)\, dx$$

Integral((x^2 + 3*x*y)*d*y, (x, d, 1))

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

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

$\frac{d x^{2} y \left(2 x + 9 y\right)}{6}$
Add the constant of integration:

$\frac{d x^{2} y \left(2 x + 9 y\right)}{6}+ \mathrm{constant}$

The answer is:

$\frac{d x^{2} y \left(2 x + 9 y\right)}{6}+ \mathrm{constant}$
