Question 10080: Hello,
I have been away from Algebra for 5 years and have completely forgotten everything. I am currently taking 2 separate 1105 college algebra and 1 1033 intermediate class but even though I am putting in so many study hours I still can't grasp the concept of these quadratic equations. Is there anywhere that I can get "info for dummy's" like me that will explain in dummy terms the different ways to solve like....(1)factoring (2)completing the square (3)square root method (4)quadratic formula. I am living on about 3 hours of sleep a night due the extra study time I am putting in on these 3 algebra classes.... (plus I am taking 3 other colleges classes and I work part-time and have a full-time 2 year old). I desparately need to find a way to understand how to do these before I get so far behind there will be no catching up. Thanks bunches and bunches
