Answer 2

Answer:

No real roots exist. The imaginary roots are $\frac{-1+\sqrt{-7}}{2}$ and $\frac{-1-\sqrt{-7}}{2}$.

Step-by-step explanation:

$x^2+x+2=0$

a=1

b=1

c=2

Discriminant; $\sqrt{b^2-4ac$

D= $\sqrt{1-8}$

Therefore, discriminant; = $\sqrt{-7}$

Hence, the roots are imaginary.

The roots are $\frac{-1+\sqrt{-7}}{2}$ and $\frac{-1-\sqrt{-7}}{2}$

Hope it helps.
