(D) x > -x

</ol>

<p>This is from the brightstorm free diagnostic test. I was really thrilled with my score for math, and this was the only one I got wrong. I don't get it though, I tested out all of these and none of them have to always be true. Let me here what you guys have to say. Is this just a really poorly written question?</p>

2

<p>E. A squared number is positive. Thus x^2 will always be greater than -x^2.</p>

3

<p>Also, don’t forget that you have to square x first before applying the negative.</p>

4

<p>Wow, that’s kind of BS. They could have at least put parenthesees around x^2.</p>
