Solving integrals/ -4*x

Integral of -4*x dx

The solution

You have entered [src]

$$\int\limits_{0}^{1} \left(- 4 x\right)\, dx$$

Integral(-4*x, (x, 0, 1))

Detail solution

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

$\int \left(- 4 x\right)\, dx = - 4 \int x\, dx$
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: $- 2 x^{2}$
Add the constant of integration:

$- 2 x^{2}+ \mathrm{constant}$

The answer is:

$- 2 x^{2}+ \mathrm{constant}$
