Answer 1

1/x+x/(x+2)=1

take LCM

`(x+2)+x^2/(x(x+2)=1`
x+2+x^2=x(x+2)

`x^2+x+2=x^2+2x`
x=2
-----------------------------------------------
2)
`1/(x-3)+1/(x+5)=x+1/x-3`


`x+5+x-3/(x+1)(x-3)=x+1/x-3`

`2x+2=(x+1)(x+5)`

`2x+2=x^2+5x+x+5`

`x^2+4x+3=0`

`x^2+3x+x+3=0`
(x+1)(x+3)=0
x= - 1, x= - 3

--------------------------------------------

3)
`3x/x^2+2x-8=1/x-2+x/x+4`

after solving both side u will get


`3x=x+4+x-2`
3x=2x+2
x=2

--------------------------------


`1/x^2-1 =2/x^2+x-2`

1/(x-1)(x+1)=2/(x-1)(x+2)
u will get same will cross out each other
1/(x+1)=2/(x+2)
(x+2)=2(x+1)
x+2=2x+2
x=0
