Explanation for the correct option:
Step 1. Find the value of sum of roots product of roots
Given that the equations have a common root
Let be the roots of and
be the roots of and
be the roots of
Step 2. Find the sum of the roots:
Since is a common root of
and
Again,
Similarly from , from and
Step 3. Find the product of the roots:
Hence, Option ‘A’ is Correct.
