(Ax + B) / (x2 + 3) is the first fraction

Plus C / (x - 1) is the second fraction

Plus D / (x - 1)^2 is the third fraction

These are the sum of the three partial fractions needed.

The workings are very long. It’s difficult to find a shorter method.

As a result, the case of two repeated roots and one non factorisagle quadratic root is NOT in your syllabus.

My final answer is the sum of the three required fractions. Each of the fractions is a part of the full original single fraction, hence the name ‘partial’.
