a,b,c

are in A.P. and if

\left( {b - c} \right){x^2} + \left( {c - a} \right)x + a - b = 0

and

2\left( {c + a} \right){x^2} + \left( {b + c} \right)x = 0

have a common root then

View answer and explanation

Correct option: B

{a^2},{c^2},{b^2}

are in A.P.

Option A (

{a^2},{c^2},{b^2}

are in A.P.) is correct because it is derived from the condition that the given quadratic equations have a common root, and

a, b, c

are in A.P.
