$$\int\limits_{0}^{1} \left(\left(\frac{7 x^{2}}{8} + \frac{x}{5}\right) - 20\right)\, dx$$

Integral(7*x^2/8 + x/5 - 20, (x, 0, 1))

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:
    
    $\int \frac{7 x^{2}}{8}\, dx = \frac{7 \int x^{2}\, dx}{8}$
    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: $\frac{7 x^{3}}{24}$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \frac{x}{5}\, dx = \frac{\int x\, dx}{5}$
    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: $\frac{x^{2}}{10}$
  The result is: $\frac{7 x^{3}}{24} + \frac{x^{2}}{10}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int \left(-20\right)\, dx = - 20 x$
The result is: $\frac{7 x^{3}}{24} + \frac{x^{2}}{10} - 20 x$
Now simplify:

$\frac{x \left(35 x^{2} + 12 x - 2400\right)}{120}$
Add the constant of integration:

$\frac{x \left(35 x^{2} + 12 x - 2400\right)}{120}+ \mathrm{constant}$

The answer is:

$\frac{x \left(35 x^{2} + 12 x - 2400\right)}{120}+ \mathrm{constant}$

$$\int \left(\left(\frac{7 x^{2}}{8} + \frac{x}{5}\right) - 20\right)\, dx = C + \frac{7 x^{3}}{24} + \frac{x^{2}}{10} - 20 x$$
