If `(lambda^2-lambda-2)x^2+(lambda+2)x lt 1` for all `x in R` then `lambda` belongs to the interval

If -3lt(x^(2)-lambdax-2)/(x^(2)+x+1)lt2 for all x inR , then the value of lambda belongs to

If -3lt(x^(2)-lambdax-2)/(x^(2)+x+1)lt2 for all x inR , then the value of lambda belongs to

If the equation x^(3)-6x^(2)+9x+lambda=0 has exactly one root in (1, 3), then lambda belongs to the interval

If the equation x^(3)-6x^(2)+9x+lambda=0 has exactly one root in (1, 3), then lambda belongs to the interval

If sin 2x cos 2x cos 4x=lambda has a solution then lambda lies in the interval

If sin2x cos2x cos4x=lambda has a solution then lambda lies in the interval

If the two roots of the equation (lambda-1)(x^(2)+x+1)^(2)-(lambda+1)(x^(4)+x^(2)+1)=0 are real and distin then lambda lies in the interval
