If 2λ1 and 2λ2 (λ1, λ2∈R and λ1λ2<0) are the roots of the equa – InterviewSolution

1.	If 2λ1 and 2λ2 (λ1, λ2∈R and λ1λ2<0) are the roots of the equation (a2+a+1)x2−4x+a=0, a∈R, then the set of values of a is
Answer» If $2^{λ_{1}}$ and $2^{λ_{2}} (λ_{1}, λ_{2} \in R and λ_{1} λ_{2} < 0)$ are the roots of the equation $(a^{2} + a + 1) x^{2} - 4 x + a = 0, a \in R,$ then the set of values of $a$ is
