Question

x power 4 -14x power 2 y power 2 + y power 4

Answer 1

$\huge\mathbb\purple{HELLO\:DEAR}$

$\huge\boxed{\texttt{\fcolorbox{Red}{aqua} {ANSWER : }}}$

✔ x⁴+y⁴-14x²y²
✔ (x²)²+(y²)²+2x²y²-16x²y²
✔ (x²+y²)²-16x²y²
✔ (x²+y²)²-(4xy) ²
✔ (x²+y²+4xy) (x²+y²-4xy) [a²-b² = (a+b) (a-b) ]

So, ultimately, your answer is :

(x²+y²+4xy) (x²+y²-4xy)
