Why is x^4 - 16 when factored not just (x^2 + 4) (x^2 - 4)?
galben [10]

Answer:

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

Step-by-step explanation:

{x}^{4}  - 16 \\  =  ({x}^{2})^{2}   -  ({2}^{2})^{2}   \\  = ( {x}^{2}  -  {2}^{2} )( {x}^{2}  +  {2}^{2} ) \\  = (x - 2)(x + 2)( {x}^{2}  + 4)

Because (x^2 - 4) = (x^2-2^2) can further be factorised as (x - 2) (x + 2).
