ANSWER

EXPLANATION
The given binomial expansion is:

Compare this to

we have a=2x , b=-3y and n=10
We want to find the coefficient of the term

This implies that, r=5.
The terms in the expansion can be obtained using

We substitute the given values to obtain;



Hence the coefficient is;

The greatest common factor is 9.

An expression having five terms which is equivalent to above term is :
The identity property of addition states that a + 0 = a
Your answer is identity property of addition.
