Question

Fatorar os polinômios colocando um fator comum em evidência
A) 13x + 13y=
B) ax² + 2xb=
C) 12xy - 10zx
D)12a³ + 6a² - 10a

Answer 1

Item A

$\begin{matrix} \underbrace{ \ \ Fator \ \ comum: \ 13 \ \ } \\\\ 13x \ + \ 13y \ \ \ \iff \ \ \ 13 \ (x \ + \ y) \end{matrix}$

Item B

$\begin{matrix} \underbrace{ \ \ Fator \ \ comum: \ x \ \ } \\\\ ax^{2} \ + \ 2xb \ \ \ \iff \ \ \ x \ ( \ ax \ + \ 2b \ ) \end{matrix}$  

Item C

$\begin{matrix} \underbrace{ \ \ Fator \ \ comum: \ x \ \ } \\\\ 12xy \ - \ 10zx \ \ \ \iff \ \ \ x \ ( \ 12y \ - 10z \ ) \end{matrix}$

Item D

$\begin{matrix} \underbrace{ \ \ Fator \ \ comum: \ a \ \ } \\\\ 12a^{3} \ + \ 6a^{2} \ - \ 10a \ \ \ \iff \ \ \ a \ ( \ 12a^{2} \ + \ 6a \ - \ 10 \ ) \end{matrix}$
