<em><u>Answer</u></em>:
The quadratic equation is : x²+x+1=0
<u><em>Step-by-step explanation:</em></u>
Generally:
let S be the sum of the roots z₁ and z₂
and P be the product of the roots z₁ and z₂
then z₁ and z₂ are the solutions for the equation: x² − Sx + P = 0
Now,
S=-1 and P=1 then the equation is x²+x+1=0.
