Question
Use the binomial theorem to expand the expressions: 
Hint:
The binomial expansion is 
.
We are asked to find the expansion of using Binomial theorem.
The correct answer is: Pascal’s triangle
Step 1 of 2:
The given expression is 
. Here, n=3. So, we would have 3+1=4 terms in the expansion. The value of 
.
Step 2 of 2:
Substitute the values in the binomial equation to get the expansion:
Thus, the expansion of the expression is 
Thus, the expansion of the expression is
The answer can also be found using the Pascal’s triangle (using the fourth row).
