In the equation x^2-6x+c=0, find the values of c that will give two imaginary solutions.
a. c >= 5
b. c > 6
c. c < 6
d. c > 9
I figured out the equation with 6 (so I believe either b or c is the answer) being there, but is would it be > or <?

Bzzt. But thanks for playing...
two imaginary solutions means the discriminant is negative:
36-4c < 0
c > 9
