What is the 8th term of the binomial expansion (x + y)10?

120x^3y^7

We can use the Pascal's triangle to solve this question.

This pascal's triangle is shown in the Image below. To build the triangle, begin with the number 1 at the top, then continue placing numbers below it in a triangular pattern. In this way, each number are the numbers directly above added together. So, the expression is :

(x+y)10

After you do the steps you be left with:

120x^3y^7

9+28x yd

Step-by-step explanation:

Assuming that they are all yard units, you just collect like terms.
