Answer 2

$\\ \green{j - (x {}^{2} -4) {}^{2} } [/ tex]</p><p>[tex] \\ \green{j - (x {}^{2} - 4) {}^{2}} \\ \green{(x {}^{2} - 4) {}^{2}}$

$\\ \green{(x {}^{2}) {}^{2} - 2x {}^{2} \times 4 + 4 {}^{2}} \\ \green {x {}^{4} - 2x {}^{2} \times 4 + 4 {}^{2}} \\ \green{(x {}^{2}) {}^{2} - 2x {}^{2} \div 4 + 4 {}^{2}} \\ \green{x {}^{4} - 8x {}^{2} + 4 {}^{2}} \\ \green{(x {}^{2} {}^{2} - 2x {}^{2} \times 4 + 4 {}^{2}} \\ \green{x {}^{2} - 8x {}^{2} + 16} \\ \green{ j -(x {}^{2} - 4){}^{2}} \\ \green{j - (x {}^{4} - 8x {}^{2} + 16)} \\ \green{j - x {}^{4} + 8x {}^{2} - 16}\\ \red{resposta} \\ \pink{j - x {}^{4} + 8x {}^{2} - 16}$
