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

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

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

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

Reorder the terms:
((-1ab + a2) + -1b * (a + -1b)) + -1(a + b)(a + b) = 0
((-1ab + a2) + -1b * (a + -1b)) + -1(a + b)(a + b) = 0
(-1ab + a2 + (a * -1b + -1b * -1b)) + -1(a + b)(a + b) = 0
(-1ab + a2 + (-1ab + 1b2)) + -1(a + b)(a + b) = 0

Reorder the terms:
(-1ab + -1ab + a2 + 1b2) + -1(a + b)(a + b) = 0

Combine like terms: -1ab + -1ab = -2ab
(-2ab + a2 + 1b2) + -1(a + b)(a + b) = 0

Multiply (a + b) * (a + b)
-2ab + a2 + 1b2 + -1(a(a + b) + b(a + b)) = 0
-2ab + a2 + 1b2 + -1((a * a + b * a) + b(a + b)) = 0

Reorder the terms:
-2ab + a2 + 1b2 + -1((ab + a2) + b(a + b)) = 0
-2ab + a2 + 1b2 + -1((ab + a2) + b(a + b)) = 0
-2ab + a2 + 1b2 + -1(ab + a2 + (a * b + b * b)) = 0
-2ab + a2 + 1b2 + -1(ab + a2 + (ab + b2)) = 0

Reorder the terms:
-2ab + a2 + 1b2 + -1(ab + ab + a2 + b2) = 0

Combine like terms: ab + ab = 2ab
-2ab + a2 + 1b2 + -1(2ab + a2 + b2) = 0
-2ab + a2 + 1b2 + (2ab * -1 + a2 * -1 + b2 * -1) = 0
-2ab + a2 + 1b2 + (-2ab + -1a2 + -1b2) = 0

Reorder the terms:
-2ab + -2ab + a2 + -1a2 + 1b2 + -1b2 = 0

Combine like terms: -2ab + -2ab = -4ab
-4ab + a2 + -1a2 + 1b2 + -1b2 = 0

Combine like terms: a2 + -1a2 = 0
-4ab + 0 + 1b2 + -1b2 = 0
-4ab + 1b2 + -1b2 = 0

Combine like terms: 1b2 + -1b2 = 0
-4ab + 0 = 0
-4ab = 0

Solving
-4ab = 0

Solving for variable 'a'.

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

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