Answer:
The roots are imaginary.
Step-by-step explanation:
given, the quadratic equation, 2x²+x+4=0
on comparing with ax²+bx+c=0
we have a=2, b=1 and c=4
=> the discriminant value, b²-4ac
= 1² - 4(2)(4)
= 1-32
= -31c , which is -ve value
if the discriminant value is negative , then the roots are imaginary.
