    I wasn't very sure on how to correctly factor these equations, but now that I looked at this site I understand.

    I dont get how you factor the quadratic equations. I get it when you have x2+5x+6. But i get confused and dont know how to do it when you have x2+5x and nothing at the end.

    You were right the quadratic formula is much easier because all I have to do is plug in the numbers then do the math.

    I am not getting how you turn things from the weird form to standard form.

    The instructions help me out alot. I had trouble just looking at the numbers, but the writing cleared it up for me alittle. tguthrie

    I did not understand how you to solve the one equation that looked like this 3x-19=6 but now I know that you need to move the six over and make all of it equal a zero. then just solve it! IT MAKES ALOT MORE SENSE!! Thank you

    okay dokey I am starting to understand this a little more.. solving bt square root. whan you just have two numbers you can move the single number over and square each side and BAM you got the qnswer. for some reason i get it more on the computer than when your talking in class. thank you

    solving quadratic equations: solving by factoring. i know see that you need to make both the factors equal zero then solve.

    So I've had alot of problems with quadratic equations but this site has helped me out alot. It breaks the steps down and explains it with examples and explinations. This has helped. Only thing I could ask for is to have a few more examples...

    so now i see that you have to make both of the equations equal to zero then solve. t.beasley

    In "completing the square" do you always times??
    Example
    (x+3)(x+3)
    Do you multiply the 3's??

    (x + 2)(x + 3) = 12
    x2 + 5x + 6 = 12
    x2 + 5x – 6 = 0
    (x + 6)(x – 1) = 0
    x + 6 = 0 or x – 1 = 0
    x = –6 or x = 1

    in this equation how do you get x squared??

    So i wasn't getting the equations that looked like this: 3x-6x=5
    But now that i looked at the examples i know that you just move the 5 over to the other side and put 0 in it's place!!!
    I'm exicited i get it now the website helped!! (:
