Need help with finding rational roots

[From: ] [author: ] [Date: 11-05-05] [Hit: ]
1.2.......
I'm terrible with math, all the rules and exceptions with so many different circumstances. I don't work well with it.

Anyways, I have a decent understanding of basic rational roots and factoring... but have trouble with, well, for example...

25b^4-34b^2+9=0


If someone could lists the steps as to how I factor and resolve this, I would appreciate it.

25b^4-34b^2+9=0
b^2(25b^2 - 34) = 9

1. b^2 = 9

b = 3

2. 25b^2 = 34

b^2 = 34/25

b = sq rt of 34/25
