(Z+1)(z-1)=

Solution for (Z+1)(z-1)= equation:

Simplifying
(Z + 1)(z + -1) = 0

Reorder the terms:
(1 + Z)(z + -1) = 0

Reorder the terms:
(1 + Z)(-1 + z) = 0

Multiply (1 + Z) * (-1 + z)
(1(-1 + z) + Z(-1 + z)) = 0
((-1 * 1 + z * 1) + Z(-1 + z)) = 0
((-1 + 1z) + Z(-1 + z)) = 0
(-1 + 1z + (-1 * Z + z * Z)) = 0
(-1 + 1z + (-1Z + zZ)) = 0

Reorder the terms:
(-1 + -1Z + 1z + zZ) = 0
(-1 + -1Z + 1z + zZ) = 0

Solving
-1 + -1Z + 1z + zZ = 0

Solving for variable 'Z'.

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

Add '1' to each side of the equation.
-1 + -1Z + 1z + 1 + zZ = 0 + 1

Reorder the terms:
-1 + 1 + -1Z + 1z + zZ = 0 + 1

Combine like terms: -1 + 1 = 0
0 + -1Z + 1z + zZ = 0 + 1
-1Z + 1z + zZ = 0 + 1

Combine like terms: 0 + 1 = 1
-1Z + 1z + zZ = 1

Add '-1z' to each side of the equation.
-1Z + 1z + -1z + zZ = 1 + -1z

Combine like terms: 1z + -1z = 0
-1Z + 0 + zZ = 1 + -1z
-1Z + zZ = 1 + -1z

Reorder the terms:
-1 + -1Z + z + zZ = 1 + -1z + -1 + z

Reorder the terms:
-1 + -1Z + z + zZ = 1 + -1 + -1z + z

Combine like terms: 1 + -1 = 0
-1 + -1Z + z + zZ = 0 + -1z + z
-1 + -1Z + z + zZ = -1z + z

Combine like terms: -1z + z = 0
-1 + -1Z + z + zZ = 0
