(6-b)*(6+b)=

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

Simplifying
(6 + -1b)(6 + b) = 0

Multiply (6 + -1b) * (6 + b)
(6(6 + b) + -1b * (6 + b)) = 0
((6 * 6 + b * 6) + -1b * (6 + b)) = 0
((36 + 6b) + -1b * (6 + b)) = 0
(36 + 6b + (6 * -1b + b * -1b)) = 0
(36 + 6b + (-6b + -1b2)) = 0

Combine like terms: 6b + -6b = 0
(36 + 0 + -1b2) = 0
(36 + -1b2) = 0

Solving
36 + -1b2 = 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 + -1b2 = 0 + -36

Combine like terms: 36 + -36 = 0
0 + -1b2 = 0 + -36
-1b2 = 0 + -36

Combine like terms: 0 + -36 = -36
-1b2 = -36

Divide each side by '-1'.
b2 = 36

Simplifying
b2 = 36

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