Q)  Find the sum and product of the roots of the quadratic equation 2x² – 9x + 4 = 0.

Ans: 

We know that sum of roots (α + β) = 

   Sum of roots =  =

Next, we know that the product of the roots (α x β) =

   Product of the roots = = 2

Therefore, the sum of roots is and product of the roots is 2.
