How do you integrate #int (x-9)/((x+8)(x-7)(x-5)) # using partial fractions?
To Integrate, partial fractions are required, which can be done as follows: Let,
Comparing like coefficients, it would be
A+B+C=0, -12A +3B +C=1 and 35A -40B-56C=-9. Solving for A,B and C, it would be
The given integral would thus be
