JEE Math Practice Question
The parabolas : $a x^2+2 b x+c y=0$ and $d x^2+2 e x+f y=0$ intersect on the line $y=1$. If $a, b, c, d, e, f$ are positive real numbers and $a, b, c$ are in G.P., then :
- A.$\frac{d}{a}, \frac{e}{b}, \frac{f}{c}$ are in A.P.
- B.$\frac{d}{a}, \frac{e}{b}, \frac{f}{c}$ are in G.P.
- C.$d, e, f$ are in A.P.
- D.$d, e, f$ are in G.P.
