Partial Fraction Decomposition: Rules for Multiple Fractions

[1MileCrash]

I hope its not a problem if I don't have an actual problem. I have a question about partial fractions.

When I spilt it into two, the numerator of the original is equal to unknown constant A times secondimerator, plus unknown constant b times first denominator.

What if it is spilt into three fractions? What constant gets multiplied by what denominator?

If f/(p.q.r) = A/p + B/q + C/r

then multip both sides by pqr to get

f = A.qr + B.pr + C.pq

So, multiply by the other two for all three? I had hoped that was the case. Hard to tell what my book did..

You can scan that part of the book that you do not understand.
