Witam potrzebuje pomocy z zadania z matematyki jest ono nastepujace:
xdo kwadratu-x+3xdo kawdratu-2x+1=
2ab-b+ab+b+ab=
3(a+1)-2(a+2)=
jedna druga(6x+4y)-(y+x)=
" Life is not a problem to be solved but a reality to be experienced! "

x2-x+3x2-2x+1=4x2-3x+1
2ab-b+ab+b+ab=4ab
3(a+1)-2(a+2)=3a+3-2a-4=a-1
1/2(6x+4y)-(y+x)=3x+2y-y-x=2x+y
