Question

I don’t get the second question.

Answer 1

Good morning,

Answer:

The quadratic equation is : x²+x+1=0

Explanation:

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.
