Answer:
Simplifying
k2 + -4k + -12 = 0
Reorder the terms:
-12 + -4k + k2 = 0
Solving
-12 + -4k + k2 = 0
Solving for variable 'k'.
Factor a trinomial.
(-2 + -1k)(6 + -1k) = 0
Subproblem 1
Set the factor '(-2 + -1k)' equal to zero and attempt to solve:
Simplifying
-2 + -1k = 0
Solving
-2 + -1k = 0
Move all terms containing k to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + -1k = 0 + 2
Combine like terms: -2 + 2 = 0
0 + -1k = 0 + 2
-1k = 0 + 2
Combine like terms: 0 + 2 = 2
-1k = 2
Divide each side by '-1'.
k = -2
Simplifying
k = -2
Subproblem 2
Set the factor '(6 + -1k)' equal to zero and attempt to solve:
Simplifying
6 + -1k = 0
Solving
6 + -1k = 0
Move all terms containing k to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + -1k = 0 + -6
Combine like terms: 6 + -6 = 0
0 + -1k = 0 + -6
-1k = 0 + -6
Combine like terms: 0 + -6 = -6
-1k = -6
Divide each side by '-1'.
k = 6
Simplifying
k = 6
Solution
k = {-2, 6}
