1.	Let α, β be the roots of the equation x2+x+1=0. Then for y≠0 in R, ∣∣∣∣y+1αβαy+β1β1y+α∣∣∣∣is equal to:
Answer» Let $α, β$ be the roots of the equation $x^{2} + x + 1 = 0$ . Then for $y \neq 0$ in R, $∣ ∣∣ ∣ \begin{matrix} y + 1 & α & β α & y + β & 1 β & 1 & y + α \end{matrix} ∣ ∣∣ ∣$ is equal to:
