Question

2. The quadratic equation x2 + x + 1 = 0 has no real root​

Answer 1

x^2+x+1=0

discriminant = b^2-4ac

= 1-4

=-3

so the given quadratic equation has imaginary roots( complex roots)

Answer 2

Answer:

The given equation is x^2+x+1=0

This is of the form ax^2+ bx +c =0, where a =1 , b= 1 and c = 1.

:. D = b^2-4ac

= (1)^2 - 4×1×1

= 1- 4

= -3

No real roots = D < 0

= -3 < 0

HENCE, THE GIVEN EQUATION HAS NO REAL ROOTS.
