Question 645592: I'm working on quadratic equations with one variable using the quadratic formula. The step I am stuck on involves square roots. The step is as follows: y = -4 plus or minus the square root of -24 over (divided by) 4. I know that the answer (the software I use allows me to see the solution)is y = -4 plus or minus 2 square root of 6 i over 4. What I don't get is where the 2 in front of the square root symbol comes from. I have encountered a few of these problems and cannot work the solution out on my own.
