If one zero of the quadratic polynomial x*+3x+k is 2, find the value o – InterviewSolution

1.

If one zero of the quadratic polynomial x*+3x+k is 2, find the value ofk.

Answer»

Given that one zero of polynomial x^2 + 3x + k is 2

Then,For x = 2 given polynomial will be equal to 0

Hence,(2)^2 + 3(2) + k = 04 + 6 + k = 0k = - 10

Therefore, value of k = - 10
