Hello. I don't claim to be a specialist and I don't claim to know what I'm talking about--unless I do. I'm not going to fill your head with a bunch of bull just becuase I don't know what I'm talking about, I will refer you to someone else. Feel free to contact me by messenger, i'm usually logged onto them via cell phone but will hop on a computer if possible. Anything else, ask

i'm reviewing for a BIG test i have in math class tomorrow and i can't for the life of me figure out how to do these two problems.
square root of 12. i know the answer is "2 root 3" but i don't remember how you get that.
and when you are using the quadratic formula. the "B squared + or - the square root of B squared + 4 x A x C. all over 2a." if you don't know the quadratic formula then don't answer this. but i substituted the numbers into the formula correctly but i got a negative under the square root and i don't remeber how to simplify it now.
thanks so much!! the test is tomorrow 8[ (link)

it looks like you have enough help on simplifying radicals (square roots) So I'll help you with the quadratic formula.
If you come up with a negative number under your square root sign, it's called an imaginary number. I'm not sure what grade level of math your in, so if this is something you haven't learned, i'm sorry. I'm in a pre-calculus class. Imaginary numbers are labeled with an "i" For example::
If you get the square root of -16, it would simplify down to "4i" You would just take the square root of 16 as normal but instead of it just being 4, it would be imaginary 4, noted as "4i"
