Question

The coefficients in the expansion of (x+y)5 are

Answer 1

i believe 5 is the coefficient as the coefficient is always then number thats in the expression next to the variables

Explanation:

Answer 2

Answer:
`1,5,10,10,5,1`

Explanation:

By definition, we know that:

`(a + b)^5 = a^5 + 5a^4b + 10a^3b^2 + 10a^2b^3 + 5ab^4 + b^5`

In this case we can identify that:

`a=x\\b=y`

Then, we can expand the binomial:

`(x+y)^5 = x^5 + 5x^4y + 10x^3y^2 + 10x^2y^3 + 5xy^4 + y^5`

Since the a coefficient is the numerical value of a term, we can identify that the coefficients of the expansion are:

`1,5,10,10,5,1`
