Homework Help: Maths

Posted by Neee on Thursday, August 12, 2010 at 6:37pm.

Solve the given equation:
ln(x + 4) + ln(x + 2) = 2

ps - we aren't allowed calculators

My ans:

I got as far as

ln [(x+4)(x+2)] = 2
ln (x^2+6x+8) = 2

And then I am lost, whatever I do ends up with no answer.
I also rewrote the above so that it is

e^2 = x^2+6x+8

But of course that made it worse :(
