(-1)/((x+2))>0

Solution

\frac{- 1}{( x + 2 )} > 0

Solution

x < - 2

+1

Interval Notation

(- \infty, - 2)

Solution steps

\frac{- 1}{x + 2} > 0

Multiply both sides by

- 1

(reverse the inequality)

\frac{( - 1 ) ( - 1 )}{x + 2} < 0 \cdot (- 1)

Simplify

\frac{1}{x + 2} < 0

If

\frac{1}{a} < 0

then

a < 0

x + 2 < 0

Move

2

to the right side

x < - 2

\frac{1}{( 3 x + 1 )} - \frac{1}{( 3 x - 1 )} \geq 2

((x-3)(x-4))/((2x^2-4x+5))>0

\frac{( x - 3 ) ( x - 4 )}{( 2 x ^{2} - 4 x + 5 )} > 0

(x^2-2x)(3x-6)<= 0

(x^{2} - 2 x) (3 x - 6) \leq 0

((x-1))/((x-2))+((x+1))/((3-x))<= 1

\frac{( x - 1 )}{( x - 2 )} + \frac{( x + 1 )}{( 3 - x )} \leq 1
