Answer:

Hey Mate,

If the question is x+1 whole divided by x ,then:

x+1 = -2x (cross-multiplication)

1 = -2x-x

1 = -3x

x = -1/3

If the question is x+ 1/x then,

x^2 + 1 whole divided by x = -2

x^2 + 1 = -2x (cross-multiplication)

x^2 + 2x + 1 =0 (which will become a quadratic equation)

x^2 + 1x + 1x+1=0

Taking common,

x(x+1)+ 1(x+1)=0

(x+1) (x+1) = 0

Therefore,

x= -1

Hope it helps...
