Answer 1

$\huge\mathcal\pink{\boxed{\boxed{\boxed{Hlo\:Madhu}}}}$

$\huge\bf\purple{Merry \: Christmas \: :-)}$

$\huge\mathcal\green{\boxed{Answer\:---}}$

$1) {x}^{4} - {y}^{4}$

= (x²)² - (y²)²

= (x² + y² ) ( x² - y² )

= (x² + y² ) ( x + y ) ( x - y )

2) = 49x² - 16 / 25

= ( 7x )² - ( 4 / 5 )

= ( 7x - 4 / 5 ) ( 7x + 4 / 5 )

$\huge\mathcal\purple{Hope\: it \:helps\:....}$

$\huge\mathcal\red{Please\:mark\:as\:the}$

$\huge\mathcal\green{\boxed{\boxed{brainliest\: (rate)}}}$
