(x-b)(x+b)=

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

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

Reorder the terms:
(-1b + x)(x + b) = 0

Reorder the terms:
(-1b + x)(b + x) = 0

Multiply (-1b + x) * (b + x)
(-1b * (b + x) + x(b + x)) = 0
((b * -1b + x * -1b) + x(b + x)) = 0

Reorder the terms:
((-1bx + -1b2) + x(b + x)) = 0
((-1bx + -1b2) + x(b + x)) = 0
(-1bx + -1b2 + (b * x + x * x)) = 0
(-1bx + -1b2 + (bx + x2)) = 0

Reorder the terms:
(-1bx + bx + -1b2 + x2) = 0

Combine like terms: -1bx + bx = 0
(0 + -1b2 + x2) = 0
(-1b2 + x2) = 0

Solving
-1b2 + x2 = 0

Solving for variable 'b'.

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

Add '-1x2' to each side of the equation.
-1b2 + x2 + -1x2 = 0 + -1x2

Combine like terms: x2 + -1x2 = 0
-1b2 + 0 = 0 + -1x2
-1b2 = 0 + -1x2
Remove the zero:
-1b2 = -1x2

Divide each side by '-1'.
b2 = x2

Simplifying
b2 = x2

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