Is the above correct? If so, I solved to get x <= 7/5, x>= -1, x <= 03, x >= 7/5. However, 4GMAT seems to solve this by squaring the absolute values on both sides of the equation....please comment...

Since you have to consider 4 different scenarios for absolute value problems like this one above, squaring it and then solving is faster. _________________

I'm aware of the solution by squaring. Are we sure that it provides a solution with all possible values of x?

If you square absolute values, the final equation will have exactly the same roots as the original. However if some of the variables are not in absolute values, you can end up with more roots then the original (consider |x|=2x+1 ). But you will never lose a root because of squaring.
