Solution for f(x)=ln(x)+ln(3-x) equation:


Simplifying
f(x) = ln(x) + ln(3 + -1x)

Multiply f * x
fx = ln(x) + ln(3 + -1x)

Multiply ln * x
fx = lnx + ln(3 + -1x)
fx = lnx + (3 * ln + -1x * ln)
fx = lnx + (3ln + -1lnx)

Reorder the terms:
fx = 3ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
fx = 3ln + 0
fx = 3ln

Solving
fx = 3ln

Solving for variable 'f'.

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

Divide each side by 'x'.
