If a root of the equation

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

be reciprocal of a root of the equation

a'{x^2} + b'x + c' = 0

, then

View answer and explanation

Correct option: A

{\left( {cc' - aa'} \right)^2} = \left( {ba' - cb'} \right)\left( {ab' - bc'} \right)

Option A (

{\left( {cc' - aa'} \right)^2} = \left( {ba' - cb'} \right)\left( {ab' - bc'} \right)

) is correct because it represents the condition when one root of the first quadratic is the reciprocal of a root of the second quadratic.
