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


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

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

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

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

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

Solving
-2ab + a2 + 1b2 = y

Solving for variable 'a'.

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