There's no error here if you copied the question correctly. The roots of this equation are complex.
 
The roots of this equation are complex, but you should be aware that the Quadratic Formula is not the one you typed: it is

[tex] \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

The version you have could cause you massive grief in the future.
 
yes sorry i ment that formula. So this equation has no roots(complex)
 
It has no real number roots which was the question (I think) you intended to pose.
