According to Wolfram Alpha, 12ln(|2x+3|)=ln(√|2x+3|)
is always true, which makes sense given what I know of log rules.
However, if I add the expression ln(√|2x−5|) to both sides of that equation, as such: ln(√|2x−5|)+12ln(|2x+3|)=ln(√|2x−5|)+ln(√|2x+3|)
WA tells me that the two sides of this equation are not always equal! How is this possible if 12ln(|2x+3|)=ln(√|2x+3|) is always true and I'm adding the same expression to both sides of the equation?
What's going on here?
