(c-6)(c+6)=

Solution for (c-6)(c+6)= 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'.
