Question

Calcule Os Produtos Abaixo .
a) 5.( 6x-2 )
b) m² . ( m - n )
c) ( 6a² + 10ab + b² ) . ( - 3/4a )

Answer 1

A) 5 . ( 6x - 2 )
30x - 10


b) m² . ( m - n )
m³ - m²n


c) ( 6a² + 10ab + b² ) . ( - 3/4a )
-18a²/4a - 30ab/4a - 3b²/4a
-9a/2 - 15b/2 - 3b²/4a

Answer 2

A)5.(6x-2)=

=5.6x+5.(-2)

=*30x-10*

B)m^2.(m-n)=

=m^2.m+m^2.n

=*m^3-m^2n*

C)(6a^2+10ab+b^2).(-3/4 a)=

=-18a^2/4a-30ab/4a-3b^2/4a

=*-9a^3/2-15a^2b/2-3ab^2/4*
