Aquadratic equation has a discriminant of -1. which answer describes the number and type of the solution of the equation? 1 real solution2 real solution 1 real and 1 complex solution 2 complex solution

We can determine number of solutions of a quadratic equation using the discriminant. 
If the discriminant is negative, there is no real solution, meaning that both solutions are complex.

If the discriminant is zero, there is 1 real solution, meaning that the other solution is complex.

If the discriminant is positive, there are 2 real solutions.

In this case, the discriminant is -1 which is negative. So there is no real solution. That means there are two complex solutions.
