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


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

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

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

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

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

Solving
2ab + 1a2 + 1b2 = 0

Solving for variable 'a'.

Factor a trinomial.
(a + b)(a + b) = 0

Subproblem 1

Set the factor '(a + b)' equal to zero and attempt to solve: Simplifying a + b = 0 Solving a + b = 0 Move all terms containing a to the left, all other terms to the right. Add '-1b' to each side of the equation. a + b + -1b = 0 + -1b Combine like terms: b + -1b = 0 a + 0 = 0 + -1b a = 0 + -1b Remove the zero: a = -1b Simplifying a = -1b

Subproblem 2

Set the factor '(a + b)' equal to zero and attempt to solve: Simplifying a + b = 0 Solving a + b = 0 Move all terms containing a to the left, all other terms to the right. Add '-1b' to each side of the equation. a + b + -1b = 0 + -1b Combine like terms: b + -1b = 0 a + 0 = 0 + -1b a = 0 + -1b Remove the zero: a = -1b Simplifying a = -1b

Solution

a = {-1b, -1b}
