URGENT HELP NEEDED PLZ

3^(x+2)=3^x+3^2
3^x.3^2=3^x+3^2

Let 3^x = y

9y=y+9
Y=9/8

3^x=9/8
xln3=ln(9/8)
x=(ln(9/8))/ln3
x=0.107

Q: Solve the inequality |x – 3a| > |x – a|, given ‘a’ positive integer.

I want to confirm that our final answer will be in terms of ‘a’ , right?
I am getting the answer as x < 2a
Is it correct?

Re: Maths help available here!!! Stuck somewhere?? Ask here!

about the partial after you divided it, you'll get 1+B/(x-1)+Cx+D/(x^2+1).... I got A=1 B=-1 and its hard for me to solve C & D.... um... how do you get C&D for the partial??
