How to use it?
Inequation:
(1/(x-1))-(1/(x-2))=>(1/(x+1))-(1/(x+2))
(x^2(x+2))/(2x+3)<=0
7x<-3
(3/(x+1))<=(5/(x+2))
Identical expressions
(three /(x+ one))<=(five /(x+ two))
(3 divide by (x plus 1)) less than or equal to (5 divide by (x plus 2))
(three divide by (x plus one)) less than or equal to (five divide by (x plus two))
3/x+1<=5/x+2
(3 divide by (x+1))<=(5 divide by (x+2))
Similar expressions
(x-1)*(x-2)(x-3)/((x+1)(x+2)(x+3))>0
(3/(x+1))<=(5/(x-2))
(x-1)^3/(x+1)>0
(2*x-3)/(x+1)>1
(3/(x-1))<=(5/(x+2))
2*x+33*x+19+99/(x^2+4*x+3)<=3/(x+1)

(3/(x+1))<=(5/(x+2)) inequation

Solving inequality on a graph

Rapid solution [src]

Or(And(-2 < x, x < -1), 1/2 <= x)

$$\left(-2 < x \wedge x < -1\right) \vee \frac{1}{2} \leq x$$

(1/2 <= x)∨((-2 < x)∧(x < -1))

Rapid solution 2 [src]

(-2, -1) U [1/2, oo)

$$x\ in\ \left(-2, -1\right) \cup \left[\frac{1}{2}, \infty\right)$$

x in Union(Interval.open(-2, -1), Interval(1/2, oo))
