Given the inequality:
(−x+x)−2≥0To solve this inequality, we must first solve the corresponding equation:
(−x+x)−2=0Solve:
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
−2−0≥0-2 >= 0
but
-2 < 0
so the inequality has no solutions
