a,b,c

are in G.P., then the equations

a{x^2} + 2bx + c = 0

and

d{x^2} + 2ex + f = 0

have a common root if

\frac{d}{a},\frac{e}{b},\frac{f}{c}

are in

View answer and explanation

Correct option: A

A.P.

Option A (A.P.) is correct because if the given equations have a common root, then

\frac{d}{a}

\frac{e}{b}

\frac{f}{c}

must be in Arithmetic Progression.
