Zad.1
a) =xy+4x+3y+12
b) =mn+2mn+6n+12
c) =ab-3a-7b+21
d) =6+4y+3x+2xy
e) =15m-5mn+3-n
f) =15q-10-6pq-4p
g) 6ab-8a-9b+12
Zad.2
a) =pkwadrat-2p+4p-8=pkwadrat+2p-8
b) = -3a+12+akwadrat-4a=akwadrat-7a+12
c) =2xkwadrat+6x+5x+15=2xkwadrat+11x+15
d) =8mkwadrat-20m+2m-5=8mkwadrat-18m-5
e) =20+15p-4p-3pkwadrat=-3pkwadrat-11p+20
Zad.3
a)=10pkwadrat+4pq+15pq+6qkwadrat=10pkwadrat+6qkwadrat+19pq
b)=3akwadrat-12ab+2ab-8bkwadrat=3akwadrat-8bkwadrat-10ab
c)=6x-4xy-9xy+6ykwadrat=6ykwadrat+6x-13xy
d)=5mkwadrat+2mn+10mn-4nkwadrat=5mkwadrat-4nkwadrat-8mn
e)=10akwadratb+15akwadrat-2bkwadrat-3ab
Tylko nie wiem czy dobrze podpunkt e z 3 zadania.
