We have
.
First let us factor the 2 to obtain,

We can now see clearly that the expression inside the parentheses is a difference of two squares.
We now write the 4 as 2². So that we obtain the expression,

Recall that

Hence our expression becomes,

Therefore, when factored completely,

Answer:
can you explain it more clear? ;)
Step-by-step explanation:
Cost = number of objects x price per object
$1,475 = x boxes * $25
x = 1,475/25 = 59 boxes of diapers
The answer will be calculated by Pythagoras theorem here -
