    Wow.  I am still very confused.  Why would you divide?  This has been the hardest thing in math I have done.  Thanks for answering, though!

    Completely Simplifying Quadratics

    This was listed as the final answer for a Quadratic Equation: So, why did they not simplify this further (to -1/-2)?  I thought you were supposed to.  Will it not be the same answer?  As long as it...

    3. What does -∞ mean? (negative infinity?)

    What does -∞ mean? (negative infinity?)

    С отговор
