Use Pascal’s triangle to expand the expression 
The correct answer is: Thus, the expansion is:
ANSWER:
Hint:
Pascal's Triangle is a method to know the binomial coefficients of terms of binomial expression (x + y)n, where n can be any positive integer and x,y are real numbers. Pascal Triangle is represented in a triangular form, it is kind of a number pattern in the form of a triangular arrangement.
We are asked to find the expansion of the expression
using Pascal’s triangle.
Step 1 of 2:
The given expression is
. Here, the value of n=5. Thus, there would be 5+1=6 terms.
Hence, we should use the sixth row of the Pascal’s triangle to write the corresponding expansion.
Step 2 of 2:

Analyzing the figure, we have:


Thus, the expansion is:
Note:
The answer can be found using the binomial expansion of
where
.
