Answer 1

Resposta:

a. Fator comum: 6.

\begin{gathered} = 6x {}^{2} + 6y {}^{2} \\ \boxed{ = 6(x {}^{2} + y {}^{2} )}\end{gathered}

=6x

2

+6y

2

=6(x

2

+y

2

)

b. Fator comum: a².

\begin{gathered} = a {}^{3} + 3a {}^{2} b \\ \boxed{ = a {}^{2} \: . \: (a + 3b)}\end{gathered}

=a

3

+3a

2

b

=a

2

.(a+3b)

c. Fator comum: y.

\begin{gathered} = y {}^{2} - xy + 2y \\ \boxed{ = y \: . \: (y - x + 2)}\end{gathered}

=y

2

−xy+2y

=y.(y−x+2)

d. Fator comum: 7a³m³.

\begin{gathered} = 35a {}^{4} m {}^{3} + 14a {}^{3} m {}^{4} \\ \boxed{ = 7a {}^{3} m {}^{3} \: . \: (5a + 2m) }\end{gathered}

=35a
