Is x2 /|x| < 1?
If x &#8800; 0, is x2 /|x| < 1?
(1) x <1> &#8722;1
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.

Sorry, there is a type error in the question .... it should be read as ...
Is x^2 /|x| < 1?

still...

that can't possibly be how the question is written.

until you can input it correctly, just know that x^2/lxl will always equal lxl, so it has to follow that -1<x<1.
It must have been love...but it's over now!
