### Write partial fraction

How to write this as a partial fraction. I'm not sure how I would do this with more than two unknowns. Since I need to find a third numerator. I can't split it into three fractions with 3 variables as numerators and isolate them.

Hi;

Do you know how to solve simultaneous equations? Or have you seen the cover up rule?

Thanks all done. Actually the original method I was using works but is just long and tedious. Thanks for the help and information.

Hi;

What happened to the problem? It is no longer there.
