2)dati nr 3 factor comun
3y+3x
3a+3b
3c-3d​

Answer 1

Explicație pas cu pas:

1.

2x+2y = 2( x+y)

2b-2c = 2(b-c)

2x35+2x65 = 2(35+65)

719x2-717x2 =2(719-717)

2x999+2 =2(999+1)

2n+2 =2(n+1)

2+2h =2(1+h)

2+22z=2(1+11)

2a+2b+2c=2(a+b+c)

8m-2 =2(4m-1)

14-10a =2(14-5a)

30x-2 =2(15x-1)

30x-34 =2(15x-34)

2.

3y+3x =3(y+x)

3a+3b =3(a+b)

3c-3d =3(c-d)

Sper să fie bun !
