Verified answer

-15/(Х+1)^2-3≥0

-15/x^2+2x+1-3≥0

-15/x^2+2x-2≥0

-(15/x^2+2x-2)≥0

15/x^2+2x-2<=0

x^×+2x-2<0

x^2+2x-2=0

x=-1+ корень из 3

x=-1- корень из 3

1(х-(-1+ корень из 3))*(х-(-1- корень из 3))<0

(х+1-корень из 3)*(х+1+корень из 3)<0

{х+1-корень из 3<0
{x+1+корень из 3>0

{х+1- корень из 3>0
{х+1+корень из 3<0

{x<-1+ корень из 3
{х>-1- корень из 3

{х>-1-корень из 3
{x<-1-корень из 3

x принадлежит (-1- корень из 3, -1+корень из 3)
х принадлежит перечеркнутый ноль

Ответ:x принадлежит (-1- корень из 3, -1+корень из 3)
