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


Simplifying
a + -1m = (a + m)(a + -1m)

Multiply (a + m) * (a + -1m)
a + -1m = (a(a + -1m) + m(a + -1m))
a + -1m = ((a * a + -1m * a) + m(a + -1m))

Reorder the terms:
a + -1m = ((-1am + a2) + m(a + -1m))
a + -1m = ((-1am + a2) + m(a + -1m))
a + -1m = (-1am + a2 + (a * m + -1m * m))
a + -1m = (-1am + a2 + (am + -1m2))

Reorder the terms:
a + -1m = (-1am + am + a2 + -1m2)

Combine like terms: -1am + am = 0
a + -1m = (0 + a2 + -1m2)
a + -1m = (a2 + -1m2)

Solving
a + -1m = a2 + -1m2

Solving for variable 'a'.

Reorder the terms:
a + -1a2 + -1m + m2 = a2 + -1m2 + -1a2 + m2

Reorder the terms:
a + -1a2 + -1m + m2 = a2 + -1a2 + -1m2 + m2

Combine like terms: a2 + -1a2 = 0
a + -1a2 + -1m + m2 = 0 + -1m2 + m2
a + -1a2 + -1m + m2 = -1m2 + m2

Combine like terms: -1m2 + m2 = 0
a + -1a2 + -1m + m2 = 0

The solution to this equation could not be determined.
