(b+6)(b-6)=

Solution for (b+6)(b-6)= equation:

Simplifying
(b + 6)(b + -6) = 0

Reorder the terms:
(6 + b)(b + -6) = 0

Reorder the terms:
(6 + b)(-6 + b) = 0

Multiply (6 + b) * (-6 + b)
(6(-6 + b) + b(-6 + b)) = 0
((-6 * 6 + b * 6) + b(-6 + b)) = 0
((-36 + 6b) + b(-6 + b)) = 0
(-36 + 6b + (-6 * b + b * b)) = 0
(-36 + 6b + (-6b + b2)) = 0

Combine like terms: 6b + -6b = 0
(-36 + 0 + b2) = 0
(-36 + b2) = 0

Solving
-36 + b2 = 0

Solving for variable 'b'.

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

Add '36' to each side of the equation.
-36 + 36 + b2 = 0 + 36

Combine like terms: -36 + 36 = 0
0 + b2 = 0 + 36
b2 = 0 + 36

Combine like terms: 0 + 36 = 36
b2 = 36

Simplifying
b2 = 36

Take the square root of each side:
b = {-6, 6}
