Question

let's See who can answer!​

Answer 1

So the questions pretty straight Forward

There Are 4 Cases

1. When Numerator is 0 and denom can be anything but zero

2.When numerator and Denominator are both zero

3.When Numerator is +ve and Denominator is -ve

4.When Numerator is -ve and Denominator is +ve

Equating for each and every case you'll get different value of lamda .

Just add the Smallest and the largest to get the answer .

(Also Note when taking something as positive in order to solve take it as >0 and vice versa I hope you know this.)
