How can I find the values for B and C in a partial fractions equation?

[rusty009]

Hey guys, I have a quick question concerning partial fractions, say i have the values A(..)+B(..)+C(..) and i can only get A b substituting a value for x, but I can not make A or C go zero or A and B go to zero at the same time, if you understand ? How do I get the values B and C ? I remember there was a way using the power of x on each side ? Thanks in advance.

Not sure if this is what you mean, but check http://www4.ncsu.edu/unity/lockers/users/f/felder/public/kenny/papers/partial.html#co-eff" out.


Good luck,
