Question

if 2x/x^2+1 = 2/x+2, what is the value of x?
a) -1/4 b)1/4 c)1/2 d) 0 e)2

Answer 1

Are there supposed to be brackets anywhere?

Answer 2

no brackets

Answer 3

Is it \[2x/(x^2+1) = 2/(x+2)\]?? or not?

Answer 4

i guess you can look at it that way

Answer 5

Well without the brackets, x can be any number except zero.

Answer 6

2x/(x2+1)=2/(x+2)
x/(x2+1)=1/(x+2)

(x2+1)/x=(x+2)
(x2+1)=x(x+2)
x2+1=x2+2x
2x=1
x=1/2
