9)-(b-2)(b+2)-2(b+4)(b+2)
10) (a+4)^2+2(a-3)(a-2)

Answer 1

1) 2v^2+10v-v^3-v^2-v+v^2+v+1=-v^3+2v^2+10v+1
2)-2x^2+2x-x^3+7x^2-49X-7x^2+49x-343=-x^3-2x^2+2x-343
3)x^2-14x+49-2x^2-4x=-x^2-18x+49
4)u^2+u-4u-4+u^3+u^2-u^2-u+u+1=u^3+u^2-3u-3
5)-c^2-10c-25-c^2-3c+4c+12=-2c^2-9c-13
6)x^2+2x+1+2x^2-2=3x^2+2x-1
7)x^3-6x^2+36x+6x^2-36x+216-2x^2+18=x^3-2x^2+234
8)2c^2+4c-6c-12-c^3-c^2-2c^2-2c-c-1=-c^3-c^2-5c-13
9)-b^2+4-2b^2-4b-8b-16=-3b^2-12b-12
10)a^2+8a+16+2a^2-4a-6a+12=3a^2-2a+28
