(c+2)(c-2)=

Solution for (c+2)(c-2)= equation:

Simplifying
(c + 2)(c + -2) = 0

Reorder the terms:
(2 + c)(c + -2) = 0

Reorder the terms:
(2 + c)(-2 + c) = 0

Multiply (2 + c) * (-2 + c)
(2(-2 + c) + c(-2 + c)) = 0
((-2 * 2 + c * 2) + c(-2 + c)) = 0
((-4 + 2c) + c(-2 + c)) = 0
(-4 + 2c + (-2 * c + c * c)) = 0
(-4 + 2c + (-2c + c2)) = 0

Combine like terms: 2c + -2c = 0
(-4 + 0 + c2) = 0
(-4 + c2) = 0

Solving
-4 + c2 = 0

Solving for variable 'c'.

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

Add '4' to each side of the equation.
-4 + 4 + c2 = 0 + 4

Combine like terms: -4 + 4 = 0
0 + c2 = 0 + 4
c2 = 0 + 4

Combine like terms: 0 + 4 = 4
c2 = 4

Simplifying
c2 = 4

Take the square root of each side:
c = {-2, 2}
