Answer:

  k = 1

Step-by-step explanation:

If k is a root, then substituting it for x will satisfy the equation.

  k² -(k +2)k +4 = 2

  k² -k² -2k +4 = 2

  -2k = -2 . . . . . . . . . subtract 4, simplify

  k = 1 . . . . . . . . divide by -2

The value of k that will make k a root of the equation is k = 1.
