I was able to simplify until it became

Then I said: Let and let

so it becomes

I don't know where to go from there. I'm trying to get a system of equation, but I can't seem to get another equation.

Thanks in advance.

Thank you, but I'm still unsure about where to go from there. How can we find a value for x?

This gives you two equations using the zero-factor property:

i)

ii)

Now, solve the two equations for real roots, and keep in mind we require . - November 20th 2012, 09:05 PMmiguel11795Re: Logarithmic Equation
Oh. I completely forgot about that property. Thank you. :)
