Oblicz:

(2ab+a)-(ab+3a)=

(b + 3b do kwadratu + (b-3b do kwadratu)=

(a+2b-3)+(2a-2b-3)=

- (2+x)- (-4-3x)=

- (5+a)- (2a-6)=

- (3x+y)+ (6x+3y)=

- (ab+3b)+(3ab-2b)=

(ab+b-a) - (ab-a+b)=

(2ab+b-3)- (b-6+2ab)=

- (2a do kwadratu + a -1)+(3a do kwadratu+a+1)=

2a+(3a-2)-(5a-6)=

xy-(x+y)+x=

Dam naj. Dzięki.
