1).Упростите:
1.(a+b+c)+(-a-b-c)=
=a+b+c-a-b-c=0
2.(a-2b+3c)-(-3a-2b+c)=
= a-2b+3c+3a+2b-c=4a-2c
3.(2x+y-3)-(y-3+x)=
= 2x+y-3-y+3-x=x
4.(a^2-2ab^2-3x)-(a^2-2ab^2+3x^2)=
= a^2-2ab^2-3x-a^2+2ab^2-3x^2=
=-3x-3x^2
5.(7-12ab+ab^2)-(14ab-ab^2-7)=
=7-12ab+ab^2-14ab+ab^2+7=
=-26ab-2ab^2
2).Упростите:
1.5a+(3a-5b+7c)-(7c-5b+3a)=
=5a
2.-(a-b)-(b-c)-(a-c)=
=-a+b-b+c-a+c=-2a+2c
3.-12x+(18-4y-12x)-(4y-12)=
=-24y-8y+30
4.18x-(32x-2a^2-18x-34)+(-18-19a^2+23x)=
=18x-32x+2a^2+18x+34-18x-
-19a^2+23x=
=-9x-17a^2+16
5.ab^2c-(4a^2bc-4abc^2)+(4a^2-4ab^2c)-ab^2c^2=
=-3ab^2c+4abc^2-ab^2c^2
