Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.in case 2, x is negative but x + 2 is positive
so modulus of x will be -x because -x is positive
but since x+2 is positive modulus of that will be x+2
so -x+x+2=2
which is always true

a good way to visualise tis would be with a graph
you can see that for values of x between -2 and 0 the expression is always equal to 2
Thanks @ri?reeeeeeeeeeeeeeeeeee Broo
So my solution is also correct?
no it isnt
Why?
I only changed the inequality signs
because in the interval, x is negative
but you were considering x to be postive
Okkk thanks bro
