I'm having difficulties solving this log. I was hoping someone could point me in the right direction

$\displaystyle lnx +ln(x+4) = 2$

$\displaystyle lx(x(x+4)) = 2$

$\displaystyle x(x+4) = e^2$

I could write that out to a sorta-polynomial of

$\displaystyle x^2 + x - e^2$

but I'm not really sure where I should be proceeding from here. Thanks in advance for any assistance.
