Solution for (c+6)(c-6)=0 equation:

Simplifying
(c + 6)(c + -6) = 0

Reorder the terms:
(6 + c)(c + -6) = 0

Reorder the terms:
(6 + c)(-6 + c) = 0

Multiply (6 + c) * (-6 + c)
(6(-6 + c) + c(-6 + c)) = 0
((-6 * 6 + c * 6) + c(-6 + c)) = 0
((-36 + 6c) + c(-6 + c)) = 0
(-36 + 6c + (-6 * c + c * c)) = 0
(-36 + 6c + (-6c + c2)) = 0

Combine like terms: 6c + -6c = 0
(-36 + 0 + c2) = 0
(-36 + c2) = 0

Solving
-36 + c2 = 0

Solving for variable 'c'.
