Answer:
Step-by-step explanation:
Given

Required
Determine the type of roots
Represent Discriminant with D; such that

D is calculated as thus

And it has the following sequence of results
When  then the roots of the quadratic equation are real but not equal
 then the roots of the quadratic equation are real but not equal
When  then the roots of the quadratic equation are real and equal
 then the roots of the quadratic equation are real and equal
When  then the roots of the quadratic equation are complex or imaginary
 then the roots of the quadratic equation are complex or imaginary
Given that  ; This means that
; This means that  and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary
 and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary
