solve plz plz plz plz plz​

Answer 1

Answer:

(x²+4+2x)(x²+4-2x)

Explanation:

x⁴+4x²+16

= x⁴+8x²+16-4x²

= [(x²)²+2*x²*4+4²]-4x²

= (x²+4)²-(2x)²

= (x²+4+2x)(x²+4-2x)

Answer 2

$\bf\huge\textbf{\underline{\underline{According\:to\:the\:Question}}}$  

x⁴ + 4x² + 16

Now factorize it to get values :-

= x⁴ + 8x² + 16 - 4x²

= (x²)² + 2 × x² × 4 + 4² - 4x²

= (x² + 4)²- (2x)²

= (x² + 4 + 2x) (x² + 4 - 2x)
