Kiiniak w przykładzie 12 widzę zły wynik, ale wiem o co chodzi, dlatego daje najlepszą :)

nella27o 4a(x+6)=(4x+24)a=4xa+24a
5a(x+7)=(5x+35)a=5xa+35a
-2a(x+8)=-(2x+16)a= -(2xa+16a)= -2xa-16a
-2a(x+9)= -(2x+18)a= -(2xa+18a)= -2xa-18a
-2a(x-1)= -(2x-2)a= -(2xa-2a)= -2xa+2a
-2a(x-2)= -(2x-4)a= -(2xa-4a)= -2xa+4a
(2x+4)*3=6x+12
(5x-4)*5=25x-20
(6x-1)*7=42x-7
(x-y)*a=xa-ya
(2x-3y)*a=2xa-3ya
(7x-5y)*a=7xa-5ya
(8x-1)*(-2)= -(8x-1)*2= -(16x-2)= -16x+2
(9x-2)*(-3)= -(9x-2)*3= -(27x-6)= -27x+6
(5-x+y)*2=10-x*2+y*2
(a+b+c)*d=ad+bd+cd
(a-b+c)*2=a*2-b*2+c*2
(a-b+c)*a=a²-ba+ca
