Answer 1

$\boxed{(a+b)^2=a^2+b^2+2ab}$

$\big(4+x^2\big)^2=\big(4\big)^2+\big(x^2\big)^2+2\big(4\big)\big(x^2\big)\ \therefore$

$\big(4+x^2\big)^2=16+x^4+8x^2$

Answer 2

Resposta:

x^4+8x^2+16x

4

+8x

+16

Explicação passo-a-passo:

(4+x^2)^2=(4+x^2).(4+x^2)=16+4x^2+4x^2+x^4 =x^4+8x^2+16(4+x 2)2

=(4+x
