a.  3x^2 ( x^8 - 16 )

b.  3x^2 ( x^2     - 2 )  (x^2 +2)( x^4   +4 )

Step-by-step explanation:

3x^10 - 48x^2

We can factor out 3 x^2

3x^2 ( x^8 - 16 )

We know the terms inside the parentheses is the difference of squares and

(a^2 -b^2) = (a-b) (a+b)

3x^2 ( x^4 ^2   - 4^2 )

3x^2 ( x^4    - 4 )( x^4   +4 )

The first term in parentheses is the difference of squares

3x^2 ( x^2 ^2    - 2^2 )( x^4   +4 )

3x^2 ( x^2     - 2 )  (x^2 +2)( x^4   +4 )
