0=a^2-2ab+b^2

Solution for 0=a^2-2ab+b^2 equation:

Simplifying
0 = a2 + -2ab + b2

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

Solving
0 = -2ab + a2 + b2

Solving for variable 'a'.
Remove the zero:
2ab + -1a2 + -1b2 = -2ab + a2 + b2 + 2ab + -1a2 + -1b2

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

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

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

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

Factor a trinomial.
(-1a + b)(a + -1b) = 0

Subproblem 1
Set the factor '(-1a + b)' equal to zero and attempt to solve:

Simplifying
-1a + b = 0

Solving
-1a + b = 0

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

Add '-1b' to each side of the equation.
-1a + b + -1b = 0 + -1b

Combine like terms: b + -1b = 0
-1a + 0 = 0 + -1b
-1a = 0 + -1b
Remove the zero:
-1a = -1b

Divide each side by '-1'.
a = b

Simplifying
a = b
Subproblem 2
Set the factor '(a + -1b)' equal to zero and attempt to solve:

Simplifying
a + -1b = 0

Solving
a + -1b = 0

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

Add 'b' to each side of the equation.
a + -1b + b = 0 + b

Combine like terms: -1b + b = 0
a + 0 = 0 + b
a = 0 + b
Remove the zero:
a = b

Simplifying
a = b
Solution
a = {b, b}
