Trzeba doprowadzić do najprostszej postaci.

1. 2(3a-4b+c)-5(3a+b-2c)=

2. 7(x+2y-3z)+4(2x-3y-5z)=

3. -3(-2a-4b-c)-6(a-2b-6c)=

4. -5(2x+2y-6z)-(x-7y-3z)=

5. 2(a-3b)-3(a-b)-5(4a+3b)=

6. -3(2x-3y)+5(x+2y)-2(3y-x)=

7. 5(y-2x)+3(x-3y)-4(2x-4y)=

8. -7(2x+3y)-9(x-2y)-3(3x+4y)=

9. 4(x'3-2x'2-5x+2)-x(2x'2-3x+5) $9. 4(x^{3}-2x^{2}-5x+2)-x(2x^{2}-3x+5)= 10. 2x(x^{2}-3x+7)+3(x^{3}-2x^{2}+4)= 11. -3x(-2x^{2}-4x+1)-5(x^{3}-3x+2)= 12. -3(x^{3}+4-2)+2x(x^{2}-3x)=$ =
