(m+2)(m-2)=0

Solution for (m+2)(m-2)=0 equation:

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

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

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

Multiply (2 + m) * (-2 + m)
(2(-2 + m) + m(-2 + m)) = 0
((-2 * 2 + m * 2) + m(-2 + m)) = 0
((-4 + 2m) + m(-2 + m)) = 0
(-4 + 2m + (-2 * m + m * m)) = 0
(-4 + 2m + (-2m + m2)) = 0

Combine like terms: 2m + -2m = 0
(-4 + 0 + m2) = 0
(-4 + m2) = 0

Solving
-4 + m2 = 0

Solving for variable 'm'.

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

Add '4' to each side of the equation.
-4 + 4 + m2 = 0 + 4

Combine like terms: -4 + 4 = 0
0 + m2 = 0 + 4
m2 = 0 + 4

Combine like terms: 0 + 4 = 4
m2 = 4

Simplifying
m2 = 4

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