Answer 1

Это не точно, но думаю, что так

Answer 2

1. 2cd^2+3cd^2-2bc^2+1,1b^2c^2+2bc^2 can be simplified to 5cd^2-b^2c^2+1
2. 3,7a^2b-3ab+2ab^2-1,2a^2b-2ab^2 can be simplified to 1,5a^2b-ab
3. x^3y^2-2xy^2-2x^3y^2+3x^2y-3x^2y-xy^2 can be simplified to -x^3y^2-3xy^2-3x^2y
4. 4mn^3+mn^3+2m^2n^3-5mn-mn-2m^2n^3 can be simplified to 5mn^3-6mn
5. ab+ab^2+a^2b-2ab-ab^2-2a^2b can be simplified to ab-a^2b
6. c^3d+cd+cd^3-3c^3d-cd-3cd^3 can be simplified to -2c^3d-2cd^3+cd
