Try plugging a value in for "a", and taking the "x" out of the middle. For instance, given |x| > 3, the books say:. . . . .
x < -3 or x > 3
Your form says:. . . . .
-3 > x > 3
...which, by making the above-mentioned change, is:. . . . .
-3 > 3
But is any
negative number greater than any
So formatting your way leads to nonsensical statements. That's why you shouldn't do that. (Plus, your teacher will probably count off, maybe a lot....)
