$$\frac{3}{x + 2} > 0$$
3/(x + 2) > 0
Detail solution
Given the inequality:
$$\frac{3}{x + 2} > 0$$
To solve this inequality, we must first solve the corresponding equation:
$$\frac{3}{x + 2} = 0$$
Solve:
Given the equation:
$$\frac{3}{x + 2} = 0$$
Multiply the equation sides by the denominator 2 + x
we get:
False

Move free summands (without x)
from left part to right part, we given:
$$0 = -3$$
This equation has no roots
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

$$\frac{3}{2} > 0$$
3/2 > 0

so the inequality is always executed
