2(k-2)(k+6)=0

Solution for 2(k-2)(k+6)=0 equation:

Simplifying
2(k + -2)(k + 6) = 0

Reorder the terms:
2(-2 + k)(k + 6) = 0

Reorder the terms:
2(-2 + k)(6 + k) = 0

Multiply (-2 + k) * (6 + k)
2(-2(6 + k) + k(6 + k)) = 0
2((6 * -2 + k * -2) + k(6 + k)) = 0
2((-12 + -2k) + k(6 + k)) = 0
2(-12 + -2k + (6 * k + k * k)) = 0
2(-12 + -2k + (6k + k2)) = 0

Combine like terms: -2k + 6k = 4k
2(-12 + 4k + k2) = 0
(-12 * 2 + 4k * 2 + k2 * 2) = 0
(-24 + 8k + 2k2) = 0

Solving
-24 + 8k + 2k2 = 0

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
Solution
k = {-6, 2}
