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


Simplifying
y2 + -1a2 = a2 + y2 + -1a(a + b)

Reorder the terms:
-1a2 + y2 = a2 + y2 + -1a(a + b)
-1a2 + y2 = a2 + y2 + (a * -1a + b * -1a)

Reorder the terms:
-1a2 + y2 = a2 + y2 + (-1ab + -1a2)
-1a2 + y2 = a2 + y2 + (-1ab + -1a2)

Reorder the terms:
-1a2 + y2 = -1ab + a2 + -1a2 + y2

Combine like terms: a2 + -1a2 = 0
-1a2 + y2 = -1ab + 0 + y2
-1a2 + y2 = -1ab + y2

Add '-1y2' to each side of the equation.
-1a2 + y2 + -1y2 = -1ab + y2 + -1y2

Combine like terms: y2 + -1y2 = 0
-1a2 + 0 = -1ab + y2 + -1y2
-1a2 = -1ab + y2 + -1y2

Combine like terms: y2 + -1y2 = 0
-1a2 = -1ab + 0
-1a2 = -1ab

Solving
-1a2 = -1ab

Solving for variable 'a'.

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

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

Factor out the Greatest Common Factor (GCF), 'a'.
a(b + -1a) = 0

Subproblem 1

Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0

Subproblem 2

Set the factor '(b + -1a)' equal to zero and attempt to solve: Simplifying b + -1a = 0 Reorder the terms: -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

Solution

a = {0, b}
