Solve the equation http://img593.imageshack.us/img593/2523/msp662119eai22g9fe584bh.gif [Broken]
The Attempt at a Solution
I tried to find the factor of the equation by substituting the factor of 9, that is +-1,+-3 and +-9 into the equation but none of them equal 0. I had no ideas how to solve it unless i get one of the roots of the equation.... Can anyone give me any hints or tips? Thanks.
