a, (2x - 1) . (3x² + 1x) =

b, (x + 1) . (3x - 2) =

c, (a - 1) . (a + 1) =

d, (x - 2) . (x + 3) =

e, (3x + 5) . (2x - 4) =

f, (x² + x) . (2x - 5) =

g, (x + 2) . (x² - 3x + 1) =

Answer 1

Resposta:

Explicação passo-a-passo:

a)  

=(2x−1)⋅(3x²+x)=

= 6x³−x²−x

b)

(x + 1) . (3x - 2)=

=3x²+x−2

c)

(a - 1) . (a + 1) =

=a²−1

d)

(x - 2) . (x + 3)=

=x²+x−6

e)

(3x + 5) . (2x - 4)=

=6x²−2x−20

f)

(x² + x) . (2x - 5)=

=2x³−3x²−5x

g)

(x + 2) . (x² - 3x + 1)=

= x³−x²−5x+2
