What have you been taught that might apply to this equation?
For example, can you obtain an expression for x squared??
Then, if you know about the imaginary number i (where i squared = -1)...do you think that you could take the square root of x squared to get two imaginary numbers as the roots of this equation?
Come on, seize the day!
