Answer 2

Answer:

your answer is a⁴ - 16 .

Step-by-step explanation:

• (a-2) (a+2) (a²+4) ​
• = (a² - 2²)(a²+4)                    [ by putting the formula (a-b)(a+b)= a²- b²]
• = (a²-4)(a²+4)
• = ( a²)² - 4²                           [ by putting the formula (a-b)(a+b)= a²- b²]  
• = a⁴ - 16 (Ans.)
