Hello, you guys can call me Azusa.; I am new to this forum. Sorry to introduce myself in such an impolite way, but I have a test at 8am later (and yes I'm pulling an all-nighter to review everything). I've focused on one area of the chapters so much that I have no idea how to do the other problems.

I appreciate any help!!

Thank You,

Azusa.

(One of the problems on the Quadratic Equations chapter).
