Question

how do I solve this? (x+y)^5

Answer 1

what constitutes a solution?

Answer 2

i think you mean expand?

Answer 3

we can use a binmial exapnsion if we wanna get fancy

Answer 4

or since its small enough; just use pascals triangle with 1 5 10 10 5 1 as your primary coefficients

Answer 5

\[x^5 +5x^4y+ 10x^3y^2 +10x^2y^3 +5xy^4 +y^5\]

Answer 6

or just cycle thru the C(n,r)s for coefficients: C(5,n)

Answer 7

thanks, i meant expand
