Question

Fatoração
1) 2ax+2ay-2axy =
2) 6x+6y+ax+ay =
3) 36a⁴-4 =
4)x²-a² =

Answer 1

Fatoração
1) 2ax+2ay-2axy =

2ax + 2ay - 2axy =
2a(x + y - xy)



2) 6x+6y+ax+ay =
6(x + y) + a(x + y)
(6 + a)(x + y)
 
3) 36a⁴-4 =

36a⁴ - 4 = ( 6a² - 2)(6a² + 2)

4)x²-a² =

x² - a²  = (x + a)(x - a)

Answer 2

1) 2a(x+y) -2(axy)                 2) 6(x+y) +a(x+y)           3)  6a2(6a2)  - 4
4) (x+a).(x-a)
