You can put this solution on YOUR website! 6 -2 -5
- = -
b b-3
----------------------
Multiply thru by b(b-3) to get:
6b(b-3) - 2(b-3) = -5b
-------
5b^2-18b-2b+6+5b = 0
---
5b^2-15b+6 = 0
----
b = [15 +- sqrt(225-4*5*6)]/10
-----
b = [15 +- sqrt(105)]/10
---
b = (3/2)+ (1/10)sqrt(105) or b = (3/2)-(1/10)sqrt(105)
