Multiple choice

If $a,b$ and $c$ are in geometrical progression and the roots of the equations $ax^{2}+2bx+c=0$ are $\alpha$ & $\beta$ and those of $ex^{2}+2bx+a=0$ are $\gamma$ and $\delta$, then

  1. $\alpha\neq \beta\neq \gamma\neq\delta$
  2. $\alpha\neq \beta\ and\ \gamma\neq\delta$
  3. $a\alpha= a\beta= c\gamma=c\delta$
  4. $\alpha= \beta\ and\ \gamma=\delta$
