ln(x-4)(x+5)=1

Solution for ln(x-4)(x+5)=1 equation:

Simplifying
ln(x + -4)(x + 5) = 1

Reorder the terms:
ln(-4 + x)(x + 5) = 1

Reorder the terms:
ln(-4 + x)(5 + x) = 1

Multiply (-4 + x) * (5 + x)
ln(-4(5 + x) + x(5 + x)) = 1
ln((5 * -4 + x * -4) + x(5 + x)) = 1
ln((-20 + -4x) + x(5 + x)) = 1
ln(-20 + -4x + (5 * x + x * x)) = 1
ln(-20 + -4x + (5x + x2)) = 1

Combine like terms: -4x + 5x = 1x
ln(-20 + 1x + x2) = 1
(-20 * ln + 1x * ln + x2 * ln) = 1
(-20ln + 1lnx + lnx2) = 1

Solving
-20ln + 1lnx + lnx2 = 1

Solving for variable 'l'.

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

Reorder the terms:
-1 + -20ln + 1lnx + lnx2 = 1 + -1

Combine like terms: 1 + -1 = 0
-1 + -20ln + 1lnx + lnx2 = 0
