    quadratic equations

    ok so when i am always solving these problems i always mess up on putting the numbers into the A, B, and C areas. well actually, i don't have a problem with putting them in, its only when i am adding and dividing i always mess up. does anyone have any helper notes that would be useful for my problem?

    or am i just going to fast, and in that case, there aren't any notes for that.

    Use extra parentheses, and write them in first. Assuming you're working in pencil, you should write \frac{-\left(\phantom{b}\right)\pm\sqrt{\left(\phantom{b}  \right)^{2}-4\left(\phantom{a}\right)\left(\phantom{c}\right)}  }{2\left(\phantom{a}\right)} very large and then stick in the a,b,c, and then start to simplify.

    Maybe you just have to be more careful.

    I used to get this problem when I first learnt the quadratic formula. Make sure you work neatly and practice it on a lot of equations and you'll know how to do it with your eyes closed eventually.

    Just practice practice.
