Answer 1

Answer:

hope this answer will be right....if yes then make it brainlist....and if not then...so sorry....

Answer 2

$\huge \underbrace \mathtt \blue{solution}$

$(x - 3)(x + 3)(x ^{2} + 9)$

according to the identity

$(a - b)(a + b) = a ^{2} - b ^{2}$

$x ^{2} - 3 ^{2} (x {}^{2} + 9)$

$(x {}^{2} - 9)(x {}^{2} + 9)$

$again \: using \: the \: same \: identity$

$(x {}^{2} ) ^{2} - 9 {}^{2}$

$x {}^{4} - 81$
