Integral(-x^2 + 4*x - 3, (x, 1, 3))

Detail solution

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

$\frac{x \left(- x^{2} + 6 x - 9\right)}{3}$
Add the constant of integration:

$\frac{x \left(- x^{2} + 6 x - 9\right)}{3}+ \mathrm{constant}$

The answer is:

$\frac{x \left(- x^{2} + 6 x - 9\right)}{3}+ \mathrm{constant}$
