set it up in the usual way
x^2-x+2 = 0
b^2-4ac = 1-8 = -7
so, what does a negative discriminant tell you?
Which statement concerning the equation x^2+2=x is true?
Its discriminant is 0 , so it has no solution.
Its discriminant is 0 , so it has one real solution.
Its discriminant is -7, so it has two complex solutions.
Its discriminant is -7, so its solutions are negative.
