wykonaj mnożenia .

temat : mnożenie sum algebraicznych xD

6(2a-6b+3c)=

(3x-2y+9)4=

3y(5x-8z-2)=

(4x-7y+7)(-2z)=

-8m(7n+9p+t)=

-2a(3a+1)+a(4a-5)=

3a(b-5a)-2a(3b+a)=

Answer 1

6(2a-6b+3c)=12a-36b+18c

(3x-2y+9)4=12x-8y+36

3y(5x-8z-2)=15xy-24yz-6y

(4x-7y+7)(-2z)=-8xz+14yz-14z

-8m(7n+9p+t)=-56mn-72mp-8mt

-2a(3a+1)+a(4a-5)=-6a(kwadrat)-3a+4a(kwadrat)-5a=-2a(kwadrat)-8a

3a(b-5a)-2a(3b+a)=3ab-15a(kwadrat)-6ab-2a(kwadrat)=-3ab-17a(kwadrat)
