Associative property of addition
<u>Step-by-step explanation:</u>
We are given the statement and we are to determine whether which of the given answer options allows it to be written as
.
According to the associative property of addition, you can add the numbers regardless of how they are grouped.
Therefore, (a + b) + c = c + (a + b) is possible with associative property of addition.
The answer is commutative - addition!
The reason it is not associative is because while the direction changes, the parentheses does not move! In the associative, the parenthesis moves, but in (a + b) + c = c + (a + b), the parenthesis contains a + b in both of them. Also here is some picture proof. (Attached)

Answer:
25x² + 144 = (5x + 12i) (5x - 12i).
Step-by-step explanation:
We have to factorize the expression 25x² + 144, using the complex number.
Now, can be treated as the complex number as there is negative value with in square root.
So,
Therefore, we can write the original expression as
25x² + 144
= 25x² - (i²)(144)
= (5x)² - (12i)²
= (5x + 12i) (5x - 12i)
So, the factorization is 25x² + 144 = (5x + 12i) (5x - 12i). (Answer)
