Find a quadratic polynomial,the sum and product of whose zeros are 3 &2

Open in App
Solution

Let the zeroes be α and β

According to the question:

α+β=3and αβ=2

The quadratic polynomial whose sum and product of the zeroes are given is given by :

x²(α+β)x+αβ

⇒ Then the quadratic polynomial will be :

x²(3)x+2

x²+3x+2

Hence, the quadratic polynomial is x2+3x+2
