I'm kind of confused as to what simplified mean? Can you please provide me with a definiton...

Like I'm kind of stumped as to what one is more simplified

-7(2x + 3) or -14x -21

Please explain what it mean for an expression to be "simplified"

The shorter the expression, usually the more simplified it is.

14x - 21
