(m+8)(m-8)=

Solution for (m+8)(m-8)= equation:

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

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

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

Multiply (8 + m) * (-8 + m)
(8(-8 + m) + m(-8 + m)) = 0
((-8 * 8 + m * 8) + m(-8 + m)) = 0
((-64 + 8m) + m(-8 + m)) = 0
(-64 + 8m + (-8 * m + m * m)) = 0
(-64 + 8m + (-8m + m2)) = 0

Combine like terms: 8m + -8m = 0
(-64 + 0 + m2) = 0
(-64 + m2) = 0

Solving
-64 + m2 = 0

Solving for variable 'm'.

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

Add '64' to each side of the equation.
-64 + 64 + m2 = 0 + 64

Combine like terms: -64 + 64 = 0
0 + m2 = 0 + 64
m2 = 0 + 64

Combine like terms: 0 + 64 = 64
m2 = 64

Simplifying
m2 = 64

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