ln(x+1)xln(x-1)=4

Solution for ln(x+1)xln(x-1)=4 equation:

Simplifying
ln(x + 1) * xln(x + -1) = 4

Reorder the terms:
ln(1 + x) * xln(x + -1) = 4

Reorder the terms:
ln(1 + x) * lnx(-1 + x) = 4

Reorder the terms for easier multiplication:
ln * lnx(1 + x)(-1 + x) = 4

Multiply ln * lnx
l2n2x(1 + x)(-1 + x) = 4

Multiply (1 + x) * (-1 + x)
l2n2x(1(-1 + x) + x(-1 + x)) = 4
l2n2x((-1 * 1 + x * 1) + x(-1 + x)) = 4
l2n2x((-1 + 1x) + x(-1 + x)) = 4
l2n2x(-1 + 1x + (-1 * x + x * x)) = 4
l2n2x(-1 + 1x + (-1x + x2)) = 4

Combine like terms: 1x + -1x = 0
l2n2x(-1 + 0 + x2) = 4
l2n2x(-1 + x2) = 4
(-1 * l2n2x + x2 * l2n2x) = 4
(-1l2n2x + l2n2x3) = 4

Solving
-1l2n2x + l2n2x3 = 4

Solving for variable 'l'.

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

Reorder the terms:
-4 + -1l2n2x + l2n2x3 = 4 + -4

Combine like terms: 4 + -4 = 0
-4 + -1l2n2x + l2n2x3 = 0

The solution to this equation could not be determined.
