Answer:
(x^4 - 16)
Step-by-step explanation:
HEY MATE!!!!
IT IS A VERY INTERESTING QUESTION BUT EASY TOO. SO LETS START SOLVING IT.
SEE THE FIRST TWO BRACKETS. THEY ARE (x+2)(x-2)
THIS MEANS THAT THEY ARE IN MULTIPLICATION.
SO WE WILL MULTIPLY THEM BY USING THE IDENTITY THAT IS:-
(a+b)(a-b)=(a^2-b^2)
SO (x+2)(x-2)= (x^2- 4)
SO MOVING FORWARD WE HAVE (x^2- 4)(x^2+4)
SO WE WILL MULTIPLY IT USING SAME IDENTITY SO IT WILL BE:-
=x^4-16
so your answer is x^4 - 16
HOPE IT HELPS
