(w+2)(w-2)=60

Solution for (w+2)(w-2)=60 equation:

Simplifying
(w + 2)(w + -2) = 60

Reorder the terms:
(2 + w)(w + -2) = 60

Reorder the terms:
(2 + w)(-2 + w) = 60

Multiply (2 + w) * (-2 + w)
(2(-2 + w) + w(-2 + w)) = 60
((-2 * 2 + w * 2) + w(-2 + w)) = 60
((-4 + 2w) + w(-2 + w)) = 60
(-4 + 2w + (-2 * w + w * w)) = 60
(-4 + 2w + (-2w + w2)) = 60

Combine like terms: 2w + -2w = 0
(-4 + 0 + w2) = 60
(-4 + w2) = 60

Solving
-4 + w2 = 60

Solving for variable 'w'.

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

Add '4' to each side of the equation.
-4 + 4 + w2 = 60 + 4

Combine like terms: -4 + 4 = 0
0 + w2 = 60 + 4
w2 = 60 + 4

Combine like terms: 60 + 4 = 64
w2 = 64

Simplifying
w2 = 64

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