I have a textbook and it takes me through the steps on what I need to do, but I still do not understand exactly why I need to do all these steps. My problem does not come from a textbook that I know of. I only havce the text for guidance. This is my problem: solve quadratic equation by using quadratic formula. x^2-x-6=0 This is what I have done so far, but I know it is not correct. x^2-x-6+6=0+6  x^2-x=6  x=6 If you could help I would greatly appreciate it. And I thank you for your time. </SPAN>\n" );
