### Question

#### The quadratic equation whose roots are I and m where l = is

### Hint:

In this question, we have to find the quadratic equation where the roots l and m are given. First we will find the value of l and m. Then to find the quadratic equation when l and m are roots we will use the form.

#### The correct answer is:

#### Given, the quadratic equation whose roots are I and m where
