Thanks scientia and noelevans
(B) When a=c we obtain ax²+bx+a= 0 which has roots
Let the roots be , , , so . Then:
So (i) and (iii) are true.
We have so is true. The others are not necessarily true: e.g. has complex roots and .
(A) If all The Roots of the equationare of unit Modulus then:
(B) If and The equation has Complex Roots Which are Reciprocal To each other, Then
