Since 25=52 then 25x=(52)x=52x So your equation reduces to 54x−52x+1=0 A simple substitution of a=52x yields a2−a+1=0 Which is a simple quadratic, solve and then back-substiute.
It's even simpler than that: 25^x = 5^4x+1 if 25^x=5^2x then 2x=4x+1 therefore you can -2x and -1 hence, 2x=-1 then /2 giving x=-1/2

Ah, I think we might be at a cross-roads here. I'm reading the equation as 25x=54x+1, you're reading it as 25x=54x+1 - it's up to the OP to clarify here.

I've been doing these last week, if it's C1 AS it'll probably be my way. If it's anything above you'll be right I Reckon Zacken.
