 Hello and welcome to the session. Let's discuss the following problem today. Find a quadratic polynomial each with a given number, the sum and product of its zero respectively that is zero comma root five. Let us hide the key idea first. We know a quadratic polynomial when the sum and product of its zeroes is given by f of x is equal to k into x square minus sum of its zeroes into x plus product of its zeroes. Now let us write the solution. It is given to us that sum of zeroes is equal to zero and product of zeroes is equal to root five. Now using our key idea let us frame up a polynomial that is f of x is equal to k into x square minus sum of zeroes is equal to zero. So zero x plus product of zeroes is equal to root five so plus root five. Now if we take this k is equal to one to satisfy our product of zeroes and sum of zeroes so we get our required polynomial as x is equal to x square plus root five. Therefore x square plus root five is our required polynomial. I hope you understood the problem. Bye and have a nice day.
