(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}
