SOLUTION: I'm homeschooled and I can't seem to get the steps of this problem. The question is: What is (x + y)^5 in expanded form? The answer is: x^5 + 5x^4y + 10x^3y^2 + 10x^2y

Question 422053: I'm homeschooled and I can't seem to get the steps of this problem.
The question is:
What is (x + y)^5 in expanded form?
The answer is:

It comes from the Binomial theorem. The expansion of is given by

(here, , number of ways to choose i objects out of n total)

In this case,
