1#x = 3 is one root of the quadratic equation x2-2kx-62 0, then find t – InterviewSolution

1.	1#x = 3 is one root of the quadratic equation x2-2kx-62 0, then find the value of k.
Answer» Since x = 3 is a solution of the question.therefore substitute 3 in place of x as it serves the equation.(3)^2 - 2k(3) - 6 = 09-6k-6 = 06k=9-6k=3/6 k = 1/2
