Solution for (4w+4)(4w-4)= equation:

Simplifying
(4w + 4)(4w + -4) = 0

Reorder the terms:
(4 + 4w)(4w + -4) = 0

Reorder the terms:
(4 + 4w)(-4 + 4w) = 0

Multiply (4 + 4w) * (-4 + 4w)
(4(-4 + 4w) + 4w * (-4 + 4w)) = 0
((-4 * 4 + 4w * 4) + 4w * (-4 + 4w)) = 0
((-16 + 16w) + 4w * (-4 + 4w)) = 0
(-16 + 16w + (-4 * 4w + 4w * 4w)) = 0
(-16 + 16w + (-16w + 16w2)) = 0

Combine like terms: 16w + -16w = 0
(-16 + 0 + 16w2) = 0
(-16 + 16w2) = 0

Solving
-16 + 16w2 = 0

Solving for variable 'w'.

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

Add '16' to each side of the equation.
-16 + 16 + 16w2 = 0 + 16

Combine like terms: -16 + 16 = 0
0 + 16w2 = 0 + 16
16w2 = 0 + 16

Combine like terms: 0 + 16 = 16
16w2 = 16

Divide each side by '16'.
w2 = 1

Simplifying
w2 = 1

Take the square root of each side:
w = {-1, 1}
