(A+1)(a-1)=0

Solution for (A+1)(a-1)=0 equation:

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

Reorder the terms:
(1 + A)(a + -1) = 0

Reorder the terms:
(1 + A)(-1 + a) = 0

Multiply (1 + A) * (-1 + a)
(1(-1 + a) + A(-1 + a)) = 0
((-1 * 1 + a * 1) + A(-1 + a)) = 0
((-1 + 1a) + A(-1 + a)) = 0
(-1 + 1a + (-1 * A + a * A)) = 0
(-1 + 1a + (-1A + aA)) = 0

Reorder the terms:
(-1 + -1A + 1a + aA) = 0
(-1 + -1A + 1a + aA) = 0

Solving
-1 + -1A + 1a + aA = 0

Solving for variable 'A'.

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

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

Reorder the terms:
-1 + 1 + -1A + 1a + aA = 0 + 1

Combine like terms: -1 + 1 = 0
0 + -1A + 1a + aA = 0 + 1
-1A + 1a + aA = 0 + 1

Combine like terms: 0 + 1 = 1
-1A + 1a + aA = 1

Add '-1a' to each side of the equation.
-1A + 1a + -1a + aA = 1 + -1a

Combine like terms: 1a + -1a = 0
-1A + 0 + aA = 1 + -1a
-1A + aA = 1 + -1a

Reorder the terms:
-1 + -1A + a + aA = 1 + -1a + -1 + a

Reorder the terms:
-1 + -1A + a + aA = 1 + -1 + -1a + a

Combine like terms: 1 + -1 = 0
-1 + -1A + a + aA = 0 + -1a + a
-1 + -1A + a + aA = -1a + a

Combine like terms: -1a + a = 0
-1 + -1A + a + aA = 0
