Solution:
The given equation with solution is
The formula used to find the roots is
If it is a quadratic equation of type , a x²+bx+c=0
→→As, both the roots , which is , satisfy the equation given.That is when you substitute the value of m in equation given , we get LHS=RHS.
So, there are no ,extraneous solution of the equation provided.
A solution set is said to be extraneous , if the roots obtained of the equation does not satisfy the equation provided.
Option (A) 0, is right choice.
