(b+8)(b-8)=

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

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

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

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

Multiply (8 + b) * (-8 + b)
(8(-8 + b) + b(-8 + b)) = 0
((-8 * 8 + b * 8) + b(-8 + b)) = 0
((-64 + 8b) + b(-8 + b)) = 0
(-64 + 8b + (-8 * b + b * b)) = 0
(-64 + 8b + (-8b + b2)) = 0

Combine like terms: 8b + -8b = 0
(-64 + 0 + b2) = 0
(-64 + b2) = 0

Solving
-64 + b2 = 0

Solving for variable 'b'.

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

Add '64' to each side of the equation.
-64 + 64 + b2 = 0 + 64

Combine like terms: -64 + 64 = 0
0 + b2 = 0 + 64
b2 = 0 + 64

Combine like terms: 0 + 64 = 64
b2 = 64

Simplifying
b2 = 64

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