let's say you have an inequality such as this:
-1< -2x^{2} < 1 and it reduces to 1/square root of 2 > x > -1/square root of 2
I understand why the inequalities can flip around but I forgot why you don't end with an imaginary number due to taking
the square root of a negative number.
It is LaTeX. Go to the LaTeX subforum.
