How do you solve #2(lnx)^2 + lnx =1#?
Use a dummy variable to put the equation into a more familiar form, then substitute back in to get to
Let's start with the original:
In one sense, this is a very complex and complicated equation. But in another sense, we can change the form of the equation to a simple trinomial by substituting a dummy variable, say A, for
now let's solve for A:
Which means that:
