Final answer:
To simplify the expression y² - 16/4 - y, we can start by simplifying the numerator. The simplified expression is y² - y - 4 after combining like terms.
Step-by-step explanation:
To simplify the expression y² - 16/4 - y, we can start by simplifying the numerator. The numerator is y² - 16/4. Simplifying the numerator gives us y² - 4. Therefore, the simplified expression is y² - 4 - y. We can further simplify it by combining like terms, which gives us the final simplified expression: y² - y - 4.
