The Method of Partial Fractions

1. The bottom polynomial can be factored, so we obtain the setup:


Multiplying by (x-4)(x+3) on both sides yields


Write the polynomial on the right in standard form:


Now we compare the coefficients of both polynomials and obtain the following system of linear equations:


Solving this system yields B=-2 and A=3.

Thus we have completed our problem:
