Question

Find the nature of roots of.
X square+X+1=0​

Answer 1

Answer:

Imaginary roots.... Because they are no real roots.

Answer 2

Answer:

The nature of roots are not real.

i.e ∆= –3

Step-by-step explanation:

On comparing with ax square + bx + c= 0,

a = 1 , b= 1 , c= 1

:.

$discriminant = b {}^{2} - 4ac$

$discriminant = (1) {}^{2} - 4(1)(1)$

:. ∆ = 1 – 4

:. ∆ = –3

Since , ∆ < 0

The nature of roots of quadratic equation are not real.
