Hey there! :)
Answer:
2nd choice. (x - 2)
Step-by-step explanation:
Given in the question:
(x²-4) ÷ (x + 2) = x-2
This is an example of difference of squares.
We can rearrange the equation by multiplying both sides by (x+2) to become:
(x² - 4) = x - 2 (x + 2)
Therefore, the binomial that must be multiplied by (x+2) is the second choice, x-2.
