To expand: The expression

Answer to Problem 29E
The expansion of the expression
Explanation of Solution
Given information: The expression is
Formula used:Binomial Theorem:
Calculation:
Here,
First write out the Pascal’s triangle such that the row that begins with 1, 4.
From the Pascal’s triangle, it is observed that the coefficients of the expression are 1, 4, 6, 4 and 1.
Expand the expression
Thus, the expansion of the expression
