McLaurin Expansion of finite sum

Click For Summary
SUMMARY

The McLaurin expansion of the series defined by the sum M Ʃ Binomial(m + q - 1, q) [(a x)^q /((a x + b)^(m + q)] for q=0 is derived using the binomial theorem. The expansion involves rewriting (a x + b)^(m + q) as a finite sum of powers of ax. To achieve the correct form, the double sum must be rearranged to group like powers of ax. This method allows for a clear representation of the series in terms of its components.

Would you please find the McLaurin expansion of the following series to help me:
M
Ʃ Binomial(m + q - 1,q) [(a x)^q /((a x + b)^(m + q)]
q=0

where M , m ℂ N^+; a, b > 0;
MANY THANKS FOR YOUR HELP.

By brute force: (ax+b)m+q can be expanded (binomial theorem) into a finite sum of powers of ax. Then rearrange double sum to keep like powers of ax together.

HOWEVER, (ax+b)^(m+q) is the denominator of a fraction.
Could you please solve this again for me.
