Question

|x|=|x-1|+|x+1|

Answer 1

how do i solve it??

Answer 2

You could square both sides and simplify, then you'll get a second degree equation to solve, that's my first idea ... x^2=((x-1)+(x+1))^2 --> x^2=(x-1)^2+2(x-1)(x+1)+(x+1)^2 (I know this looks terrible, but see if you can simplify it correctly)

Answer 3

ok, let me see...

Answer 4
