(c+8)(c-8)=

Solution for (c+8)(c-8)= 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.

Add '64' to each side of the equation.
-64 + 64 + c2 = 0 + 64

Combine like terms: -64 + 64 = 0
0 + c2 = 0 + 64
c2 = 0 + 64

Combine like terms: 0 + 64 = 64
c2 = 64

Simplifying
c2 = 64

Take the square root of each side:
c = {-8, 8}
