(a-b)2-(a+b)2=

Solution for (a-b)2-(a+b)2= equation:

Simplifying
(a + -1b) * 2 + -1(a + b) * 2 = 0

Reorder the terms for easier multiplication:
2(a + -1b) + -1(a + b) * 2 = 0
(a * 2 + -1b * 2) + -1(a + b) * 2 = 0
(2a + -2b) + -1(a + b) * 2 = 0

Reorder the terms for easier multiplication:
2a + -2b + -1 * 2(a + b) = 0

Multiply -1 * 2
2a + -2b + -2(a + b) = 0
2a + -2b + (a * -2 + b * -2) = 0
2a + -2b + (-2a + -2b) = 0

Reorder the terms:
2a + -2a + -2b + -2b = 0

Combine like terms: 2a + -2a = 0
0 + -2b + -2b = 0
-2b + -2b = 0

Combine like terms: -2b + -2b = -4b
-4b = 0

Solving
-4b = 0

Solving for variable 'b'.

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

Divide each side by '-4'.
b = 0

Simplifying
b = 0
