a) (2x + 3)2
b) (3x + 2)2
c) (5x – 3)2
d) (2y - 4)​

Answer 1

Explicação passo-a-passo:

$\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } \: \: \mathsf {OI, TUDO \: \: J\acute{O}IA \: ? \: \:\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } }$

a)

$\mathtt{(2x + 3)2} \\ \mathtt{2(2x + 3)} \\\red {\mathtt{4x + 6}}$

b)

$\mathtt{(3x + 2)2} \\ \mathtt{2(3x + 2)} \\ \red{\mathtt{6x + 4}}$

c)

$\mathtt{(5x - 3)2} \\ \mathtt{2(5x - 3)} \\ \red{\mathtt{10x - 6}}$

d)

$\mathtt{(2y - 4)} \\ \red{\mathtt{2(y - 2)}}$

$\boxed{\underline{\overline{\mathbb{_ \heartsuit^\heartsuit\: JOSÉ\:ARMANDO_\heartsuit ^{\heartsuit}}}}}$
