Series expansion

[jade cosmos]

I think I have made a mistake somewhere. Think to do with the expansion of 4(3x+2)^-1. Could someone please let me know where. The expansion only need to be for the first three terms. Thank

...what's the actual problem you're trying to solve?

[jade cosmos]

No problem

The question is just to find the series expansion up to first three terms

But I am pretty sure I have made a mistake somewhere in there

Any help?

...how is "find the series expansion up to first three terms" "no problem"? The expansion of which series?

[jade cosmos]

Expansion of the two fractions shown at the top

[wise talon]

That's not a series.

[jade cosmos]

What is it then

Binomial
