Prosze o szybkie odp. daje naj ^^

z góry dziękuje :D

Answer 1

2a-3ab+4ab-5a+2ab-7abc = -3a+ab-7abc

2a-3+7a-8-10a= -a-11

x(do kwadratu)y -2xy+ xy(do kwadratu)-5xy+3x(do kwadratu )y =4x(do kwadratu)-7xy+xy(do kwadratu)

2a - 3ab+4a ( do kwadratu)-8a-2ab = -6a-5ab+4a(do kwadratu)

4-2x+6+6x-9+5x-1= 9x

4x( do kwadratu )-5xy-7x ( dokwadratu )-xy+2 + = -3x(do kwadratu)- 6xy+2

2abc-4bca+2-6a+2a = -2abc-4a+2

Prosze ;)

Answer 2

2a-3ab+4ab-5a+2ab-7abc = -3a+3ab-7abc

2a-3+7a-8-10a= -a-11

x²y -2xy+ xy²-5xy+3x²y =xy²+4x²y-7xy

2a - 3ab+4a²-8a-2ab = 4a²-6a-5ab

4-2x+6+6x-9+5x-1= 9x

4x²-5xy-7x²-xy+2 =-3x²-6xy+2

2abc-4bca+2-6a+2a = -2abc-4a+2
