Solution for ln(4+x^2)=ln(x)+ln(4) equation: 


Simplifying
ln(4 + x2) = ln(x) + ln(4)
(4 * ln + x2 * ln) = ln(x) + ln(4)
(4ln + lnx2) = ln(x) + ln(4)

Multiply ln * x
4ln + lnx2 = lnx + ln(4)

Reorder the terms for easier multiplication:
4ln + lnx2 = lnx + 4ln

Reorder the terms:
4ln + lnx2 = 4ln + lnx

Add '-4ln' to each side of the equation.
4ln + -4ln + lnx2 = 4ln + -4ln + lnx

Combine like terms: 4ln + -4ln = 0
0 + lnx2 = 4ln + -4ln + lnx
lnx2 = 4ln + -4ln + lnx

Combine like terms: 4ln + -4ln = 0
lnx2 = 0 + lnx
lnx2 = lnx

Solving
lnx2 = lnx

Solving for variable 'l'.

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

Add '-1lnx' to each side of the equation.
-1lnx + lnx2 = lnx + -1lnx

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

Factor out the Greatest Common Factor (GCF), 'lnx'.
lnx(-1 + x) = 0
