15a-7a=a(15-7)
6x+6y-6y=6(x+y-y)
50a-25a=25a(2-1)
3x+5x-2x=x(3+5-2)
12a-16b=4(3a-4b)
18x+12z+24t=6(3x+2z+4t)

Sper ca te-am ajutat! :)
Le poți si pe acestea ? 9x+9y+9z-9a. ; 5x+10y-15a. ; 18a-27b. ; 8xy-8xz. ; 3xa +5xa -2xa
9(x+y+z-a) , 5(x+2y-3a), 9(2a-3b), 8x(y-z), xa(3+5-2)

15a-7a=a(15-7)=8a
6x+6y-6y=6(a+y-y)=6a
50a-25a=a(50-25)=25a
3x+5x-2x=x(3+5-2)=6x
12a-16b=4(3a-4b)
18x12z+24t=3(6x4z+24t)=3*24(xz+t)=72(xz+t)
