Begin completing the square.

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + 4k + -6 + k2 = 0 + -6

Reorder the terms:
6 + -6 + 4k + k2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + 4k + k2 = 0 + -6
4k + k2 = 0 + -6

Combine like terms: 0 + -6 = -6
4k + k2 = -6

The k term is 4k.  Take half its coefficient (2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
4k + 4 + k2 = -6 + 4

Reorder the terms:
