He's factoring. What the hell do you think? His order of operations is fine. I'm not terribly sure why he would give (x - y) as an exponent. |

You said it was impossible, so why don't you just use your own advice? --- End quote --- I had a revelation. --- Quote from: DrMobius on November 16, 2009, 08:51:57 PM ---Fair enough. Even so, two of its zeros are imaginary. That is what forgeted me up I guess. The zeros to a2 + ab + b2 are both at imaginary numbers. --- End quote --- |
