Question

find the value of sum of zeroes and product of zeroes if the quadratic equation is 7x²-5x+9=0 ​

Answer 1

Step-by-step explanation:

Let α,β be the zeroes of the polynomial 7x

2

+5x−2.

Then α,β be the roots of the quadratic equation 7x

2

+5x−2=0.

Then from the relation between roots and co-efficients of quadratic equation we've,

α+β=−

7

5

and α.β=−
