\[2x ^{2}+x+2=0\] is the problem.. so far i am at \[-1\sqrt{-14}\over 4\]

By using the qudratic equation, I get A = 2, B = 1, C = 2. You have it right. It is: \[-1 \pm \sqrt(-15)/4\] Since the answer in the square root is negative, it is a non-real answer or imaginary number with: \[(-1 \pm \sqrt(15 i) )\div 4\] I hope that helps...
