Question

Factorize (x+2) (x-2) (x4+4)

Answer 1

=> (x+2)(x-2)(x^4+4)
__________[it is already Factor]

-------------------------------

using algebraic identify :-

=> a²-b² = (a+b)(a-b)

-----------------------------

=> (x+2)(x-2)(x^4+4)


$= > ( {x}^{2} - {2}^{2} ).( { {x}^{2} }^{2} + {2}^{2} )$

Answer 2

using identity (a+b)(a-b) =a²-b²
it will become
(x²-2²)(x⁴+4)
(x²-4)(x⁴+4)
(x²-4)( (x²)²+ 2²)
this is ur answer ↑
