Dau coronita

Answer 1

Explicație pas cu pas:

a. 3x+3y= 3(x+y)

b. 3x-3y= 3(x-y)

c. 3xy+3ab+3= 3(xy+ab+1)

d. 3x+3y+9= 3(x+y+3)

e. -3x(2)+6xy+9y(2)= -6x+6xy+18y

6(-x+xy+3y)

f. 6x+9y-18z= 3(2x+3y-6z)

Answer 2

a)3(x+y)

b)3×(x-y)

c)3×(xy+ab+1)

d)3(x+y+3)

e)-9x+6xy+81y=3(-3x+2xy+27y)

f)3(2x+3y-6z)
