PLEASE HELP QUICKLY WILL MARK BRAINLIEST

How would you explain the steps of binomial expansion to someone who was just learning about the binomial theorem? Include as much from the lesson(s) as possible, using correct mathematical language and full, specific descriptions. This is worth 60 points of the total 100 points, so make sure you are as complete, specific and thorough as possible.

Respuesta :

From the Pascal's triangle, take the correct level. Use it to write the binomial expansion. Or use nCr.
(x+y)^n
Remember that the powers of x start at n, and that the sum of the x and y powers is always n.
