(k-6)(k+8)=0

Solution for (k-6)(k+8)=0 equation:

Simplifying
(k + -6)(k + 8) = 0

Reorder the terms:
(-6 + k)(k + 8) = 0

Reorder the terms:
(-6 + k)(8 + k) = 0

Multiply (-6 + k) * (8 + k)
(-6(8 + k) + k(8 + k)) = 0
((8 * -6 + k * -6) + k(8 + k)) = 0
((-48 + -6k) + k(8 + k)) = 0
(-48 + -6k + (8 * k + k * k)) = 0
(-48 + -6k + (8k + k2)) = 0

Combine like terms: -6k + 8k = 2k
(-48 + 2k + k2) = 0

Solving
-48 + 2k + k2 = 0
