x-x-2>=0 inequation

A inequation with variable

The solution

You have entered [src]
x - x - 2 >= 0
(x+x)20\left(- x + x\right) - 2 \geq 0
-x + x - 2 >= 0
Detail solution
Given the inequality:
(x+x)20\left(- x + x\right) - 2 \geq 0
To solve this inequality, we must first solve the corresponding equation:
(x+x)2=0\left(- x + x\right) - 2 = 0
Solve:
This equation has no roots,
this inequality is executed for any x value or has no solutions
check it
subtitute random point x, for example
x0 = 0

200-2 - 0 \geq 0
-2 >= 0

but
-2 < 0

so the inequality has no solutions
