guys i have this equation which doesn't want to solve itself. It's pretty simple really I've just gotten some sort of writer's block and the few gears that are left in my brain don't have enough power for the lightbulb to light up. Please help :

( 3 + 2(sqrt2) )^x + ( 3 - 2(sqrt2) )^x = 6^x

I know that 3 + 2(sqrt2) is the reciprocal of 3 + 2(sqrt2) i just don't know exactly where to apply it

Thanks.

I think you have to gently massage it, it's just being stubborn. Maybe give it a quickie, if you're close to it. In time, I bet it'll want to solve itself when it feels like it.
