okay so it's summer and because it's summer i forget EvErYtHiNg. anyways.....i have a question about ALGEBRA!! There's like a "therom" or a "equation" and it's like has a "4" in it and a "square root sign" in it. I NO THAT IT'S DIVIDED BY 2a.....thats all i no about it. but whats the whole thing?!help!

i would help if it made sense...
do you mean its the square root of 4 divided by 2?
the square root is 2
2 divided by 2 is one...
but if thats not what you meant sorry, i didnt really get it

It has to be the ones given by Ahab and Warelphant. Its the only basic algebra equation that fits your partial description.

Quadratic formulat solution to ax^2 + bx + c =0
x = ( b +/- sqrt(b^2 - 4ac) )/(2a)

sqrt(4)/2a = 2/2a = 1/a
