Question

simply (X+2) (x-2) (X
power 2 +4)​

Answer 1

Answer:

(x+2)(x-2)(x²+4)

= (x²-4)(x²+4)

= x⁴-16

Answer 2

Step-by-step explanation:

(x + 2) (x - 2) (x² + 4)

WE KNOW THAT

(a+b) (a-b) = a²-b²

(x+2) (x-2) = x²- 2² = x²- 4

Then

By using the same formula

(x²-4)(x²+4)= (x²)² + 4² = x⁴ - 16
