Zapisz jak najprościej: 3a-3b-6a+2b= 7a+6b-7-5a-8b= -(2xy-5x+4)+(xy+8x-2)= 4(a-2a²+2)= 3(x-2)-(x+2)+2= (16x²-4x+4)/4 (2x²+2x)/0.5x=

3a-3b-6a+2b=-3a-b 7a+6b-7-5a-8b=2a-2b-7 -(2xy-5x+4)+(xy+8x-2)=-2xy+5x-4+xy+8x-2=-xy+13x-6 4(a-2a²+2)=4a-8a²+8 3(x-2)-(x+2)+2=3x-6-x-2=2x-8 (16x²-4x+4)/4=4x²-x+1 (2x²+2x)/0.5x= 4x²+4x Powinno być dobrze. Pozdrawiam. Liczę na naj.
