(X+1)(x-1)=64

Solution for (X+1)(x-1)=64 equation:

Simplifying
(X + 1)(x + -1) = 64

Reorder the terms:
(1 + X)(x + -1) = 64

Reorder the terms:
(1 + X)(-1 + x) = 64

Multiply (1 + X) * (-1 + x)
(1(-1 + x) + X(-1 + x)) = 64
((-1 * 1 + x * 1) + X(-1 + x)) = 64
((-1 + 1x) + X(-1 + x)) = 64
(-1 + 1x + (-1 * X + x * X)) = 64
(-1 + 1x + (-1X + xX)) = 64

Reorder the terms:
(-1 + -1X + 1x + xX) = 64
(-1 + -1X + 1x + xX) = 64

Solving
-1 + -1X + 1x + xX = 64

Solving for variable 'X'.

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

Add '1' to each side of the equation.
-1 + -1X + 1x + 1 + xX = 64 + 1

Reorder the terms:
-1 + 1 + -1X + 1x + xX = 64 + 1

Combine like terms: -1 + 1 = 0
0 + -1X + 1x + xX = 64 + 1
-1X + 1x + xX = 64 + 1

Combine like terms: 64 + 1 = 65
-1X + 1x + xX = 65

Add '-1x' to each side of the equation.
-1X + 1x + -1x + xX = 65 + -1x

Combine like terms: 1x + -1x = 0
-1X + 0 + xX = 65 + -1x
-1X + xX = 65 + -1x

Reorder the terms:
-65 + -1X + x + xX = 65 + -1x + -65 + x

Reorder the terms:
-65 + -1X + x + xX = 65 + -65 + -1x + x

Combine like terms: 65 + -65 = 0
-65 + -1X + x + xX = 0 + -1x + x
-65 + -1X + x + xX = -1x + x

Combine like terms: -1x + x = 0
-65 + -1X + x + xX = 0
