What's the coefficient of the \($x^2y^4$\) term in the expansion of \((x+y)^6\)?

We can expand (x + y)^6 as (x + y)(x + y)(x + y)(x + y)(x + y)(x + y).

 

When we expand (x + y)(x + y)(x + y)(x + y)(x + y)(x + y), we find that there are 10 terms that are equal x^2*y^4.

 

So the coefficient of x^2*y^4 is 10.
