Question

What is the nature of roots of the following quadratic equation?
x^2+x+1=0

Answer 1

Step-by-step explanation:

Number of Roots of any equation in one variable depends on the maximum power of the variable in that equation . Here since it is a quadratic equation so the number of roots will be 2. The given roots have been calculated using the quadratic formula [1] . 'i' [2] signifies that the roots are complex and not real.

Answer 2

Answer:

x^2+x+1=0

a=1 , b=1 , c=1

D=b^2-4ac

D=1^2-4×1 ×1

D=1-4

D=-3

This equation has no real roots

but they are imaginery (this sentece only if your in 11th class)
