You can't find the square roots of negative numbers. If you're working with imaginary numbers then your answer will be 4 +/- 2i (square root 3) /2 which can be simplified to: 2+/- i (square root 3)
I hope that helped! =)

Not sure what you want here, but since 12 = 4 x 3, you can rewrite sqrt 12 as sqrt(4x3) which is equal to 2*sqrt3. The 4 is the perfect square.

are you sure its -12? check because c term includes the sign of c as well so that b^2 - (4*a*c) usually becomes positive...
nyways, the square root of -1 is a complex number called i...
so, your prob becomes 2 +/- [(sqrt (12) *i)/2]....
