1.Sprowadz do najprostrzej postaci;
2(4-4(3a-1))-16a*-3(3-4a)
* do potęgi drugiej
2.Sprowadż do najprostrzej postaci;
1-a(b-1)+2(-b(a+1)-0,5a)+2b

1.
2(4-4(3a-1))-16a^2-3(3-4a)=2(4-12a+4)-16a^2-9+12a=16-24a-16a^2-9+12a
=16a^2+36a+7
2.
1-a(b-1)+2(-b(a+1)-0,5a)+2b=1-ab+a+2(-ab-b)-0.5a+2b=1-ab+a-2ab-2b-0,5a+2b
=-3ab-0,5a+1
