Answer 2

HERE IS YOUR ANSWER...⬇⬇

$\underline{SOLUTION}$ ➡

$we \: know \:that \: \: \\ \\a {}^{2} - b {}^{2} = (a + b)(a - b) \\ \\ \\ \\ by \: using \: this \: formula \\ \\ \\ x {}^{4} - 16 \\ =( x {}^{2} ) {}^{2} - (4) {}^{2} \\ = (x {}^{2} - 4)(x {}^{2} + 4) \\ =( x {}^{2} - 2 {}^{2}) (x {}^{2} + 4) \\ = (x + 2)(x - 2)(x {}^{2} + 4)$



$\boxed{ANSWER}$ ➡

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