Answer 2

Answer:

1 / 2

Step-by-step explanation:

Given If x=3 is one root of the quadratic equation x^2- 2kx - 6=0 than find the value of k

 One root is given as 3, so substituting x = 3 in the given equation we have

        3^2 - 2k(3) - 6 = 0

        9 - 6k - 6 = 0

      - 6 k + 3 = 0

      - 6 k = -3

        k = 3 / 6

       k = 1 / 2

So the value of k is 1 / 2
