Me ajudem por favor!!!

Answer 1

POLINÔMIOS                             valor numérico x = 4

(1 + 1/4 x ) ( 1 - 1/4 x ) 

( 1 + 1/4 . 4 ) ( 1 - 1/4 . 4 )

( 1 + 4/4 ) ( 1 - 4/4 )

( 1 + 1 ) ( 1 - 1 )

2 . 0 =  0

Answer 2

$\ \ \ \Big(1+\frac{1}{4}x \Big)\cdot\Big(1-\frac{1}{4}x \Big)\\=\Big(1+\frac{x}{4} \Big)\cdot\Big(1-\frac{x}{4} \Big)\\=\Big(1+\frac{4}{4} \Big)\cdot\Big(1-\frac{4}{4} \Big)\\=(1+1)\cdot(1-1)\\=2\cdot0\\=0$
