Took the quiz and got it right hope this helps :) , you can check out the other answer for explanation.

Answer 2

`3(x - 2)(x + 2)( {x}^(2) + 4)`

Explanation:

`3{x}^(4) - 48`

Factor out 3 from the expression:

`3( {x}^(4) - 16)`

Using
`{a}^(2) - {b}^(2) = (a - b)(a + b)`,factor the expression

`3(( {x}^(2) ) ^(2) - {(4)}^(2) )`

`3( {x}^(2) - 4)( {x}^(2) + 4)`

Again, factor using the formula of
`{a}^(2) - {b}^(2)`

`3(x - 2)(x + 2)( {x}^(2) + 4)`

Hope this helps...

Good luck on your assignment...
