Hi all I have no idea how to start this equation the exponential equations I have done so far were all more or less the same (becomming a quadratic equation which made it very easy to solve X)

How do I start this? should I somehow devide everything by 3?

Thanks in advance

hi Deon

you should divide by anything.you ought to group stuff up here:

Hi;

2 is only one solution. There are others in the complex plane.

Hi Anonimnysteffy Thanks a lot I understand what happens now.

Can you please show me what you mean by I should group stuff?

Should I break it up like

Hi Bobbym I think that's a bit above my level at this stage...

Thanks anyhow for the reply

Hi;

That's good, cause mathematica says these are also solutions:

Where n is any integer. I was having trouble duplicating exactly how it came up with that.

We took these types of equation and how to solve them in Secondary level in School.

But I dont remember exactly how we continued with it.

Just what I remembered:

1- You have to try some numbers to place them in "x" to get 0

2- Then youve to divide this number with x example x in 1 was 3 ==> So you devide by x-3

3- Youll get Stage 1 equation mltiplied by Stage 2 Equation.

4- You have to convert the Stage 2 Equation into 2 Stage 1 Equations.

The answers will be like this form :

x±ax±bx±c=0 ---> Then x would be either a,b,c after negating them. Is possitive then they should be negative, and if negative then possitive.

Hope that helps.
