Question

04. Simplifique 2x2y + 8xy – 4xyza.
A) (2xy + x).(4 + 2z)
B) (x + 4).(x - y)
C) 2x. (y + 4 - 2)
D) 2xy. (x + 4 - 2za)
E) (xy + 2).(4 - 2xy)

Answer 1

Resposta:

A) v = 2*s + 3*a

B) x² - xy + 4x - yx

C) x² - xy + 4x - yx

D) 2x²y + 8xy - 4xyza

E) 8x²y² +2xy + 8

Explicação passo a passo:

A) (2xy + x) * 2(2 + z) =

2 * (4xy + 2xzy + 2x + xz)

B) (x+4) * (x-y) =

x² - xy + 4x - yx

C) 2x * ( y + 4 - 2) =

 2x * ( y + 2) =

2xy + 4x

D) 2xy. (x + 4 - 2za)=

2x²y + 8xy - 4xyza

E) (xy + 2).(4 - 2xy) =

4xy - 8x²y² + 8 - 2xy =

8x²y² +2xy + 8
