Question: Is this fraction less than 1?

Comment on Is this fraction less than 1?

Can't we take -1/2 if the first statement, since x>-1?

Yes, we could have also tried x = -1/2
The result would remain the same though (statement 1 is not sufficient)

Hello Brent!
Thank you for the these great videos.
What I did was to simplify the equation to see that the numerator has to be positive irrespective of what sign X carries and the denominator will retain whatever sign X carries. So, I rephrased the question to be "is X < 1?" in which case the equation will result into a figure less than 1. Of course statement 1 is not sufficient and statement 2 is.
