(m-2)(m+2)=64

Solution for (m-2)(m+2)=64 equation:

Simplifying
(m + -2)(m + 2) = 64

Reorder the terms:
(-2 + m)(m + 2) = 64

Reorder the terms:
(-2 + m)(2 + m) = 64

Multiply (-2 + m) * (2 + m)
(-2(2 + m) + m(2 + m)) = 64
((2 * -2 + m * -2) + m(2 + m)) = 64
((-4 + -2m) + m(2 + m)) = 64
(-4 + -2m + (2 * m + m * m)) = 64
(-4 + -2m + (2m + m2)) = 64

Combine like terms: -2m + 2m = 0
(-4 + 0 + m2) = 64
(-4 + m2) = 64

Solving
-4 + m2 = 64

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 = 64 + 4

Combine like terms: -4 + 4 = 0
0 + m2 = 64 + 4
m2 = 64 + 4

Combine like terms: 64 + 4 = 68
m2 = 68

Simplifying
m2 = 68

Take the square root of each side:
m = {-8.246211251, 8.246211251}
