(c-8)(c+8)=0

Solution for (c-8)(c+8)=0 equation:

Simplifying
(c + -8)(c + 8) = 0

Reorder the terms:
(-8 + c)(c + 8) = 0

Reorder the terms:
(-8 + c)(8 + c) = 0

Multiply (-8 + c) * (8 + c)
(-8(8 + c) + c(8 + c)) = 0
((8 * -8 + c * -8) + c(8 + c)) = 0
((-64 + -8c) + c(8 + c)) = 0
(-64 + -8c + (8 * c + c * c)) = 0
(-64 + -8c + (8c + c2)) = 0

Combine like terms: -8c + 8c = 0
(-64 + 0 + c2) = 0
(-64 + c2) = 0

Solving
-64 + c2 = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.
