Algebra II - Factoring and Imaginary Numbers
PostPosted: Wed Dec 07, 2005 2:36 pm
This is the first time I've ever asked for help here, but this stuff is annoying. And I have a test tomorrow. I'm going to use / for a fraction line, alright?
If I have 4 times the square root of 3 multiplied by the square root of 21, what do I do? I know that..say, the square root of six times the square root of 15 is the square root of 90, and I have to simplify it down from there. I HAVE to make a 100 on that test tomorrow to pull my grade up high enough to offset the bad one I made last 9 weeks. I have a 95 or so now. If I make a 100 here, I should have a 97, which will pull up my 82 to a 90 for the semester.
