(x+1)*(x-1)=e

Solution for (x+1)*(x-1)=e equation:

Simplifying
(x + 1)(x + -1) = e

Reorder the terms:
(1 + x)(x + -1) = e

Reorder the terms:
(1 + x)(-1 + x) = e

Multiply (1 + x) * (-1 + x)
(1(-1 + x) + x(-1 + x)) = e
((-1 * 1 + x * 1) + x(-1 + x)) = e
((-1 + 1x) + x(-1 + x)) = e
(-1 + 1x + (-1 * x + x * x)) = e
(-1 + 1x + (-1x + x2)) = e

Combine like terms: 1x + -1x = 0
(-1 + 0 + x2) = e
(-1 + x2) = e

Solving
-1 + x2 = e

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 + 1 + x2 = 1 + e

Combine like terms: -1 + 1 = 0
0 + x2 = 1 + e
x2 = 1 + e

Simplifying
x2 = 1 + e

Reorder the terms:
-1 + -1e + x2 = 1 + e + -1 + -1e

Reorder the terms:
-1 + -1e + x2 = 1 + -1 + e + -1e

Combine like terms: 1 + -1 = 0
-1 + -1e + x2 = 0 + e + -1e
-1 + -1e + x2 = e + -1e

Combine like terms: e + -1e = 0
-1 + -1e + x2 = 0
