Question

If one zero of the quadratic
polynomial x*2+ 3x + k is 2, then
the value of kis​

Answer 1

Step-by-step explanation:

Eleanor Roosevelt once said, "You must do the thing you think you cannot do." Write a narrative about a time when you did something you thought you could not do. Be sure to include specific details so that a reader can follow your story.

Answer 2

Let f(x) = x^2 + 3x + k

Given that one zero of the polynomial is 2.

That is, f(2) = 0

=> f(2) = 2

(2)^2 + 3(2) + k = 0

4 + 6 + k = 0

10 + k = 0

k = -10

Thus, the value of k for which 2 is the zero of the given polynomial is k = -10.
