Answer 1

26.2 а)x^2y^2(x+y)=x^3y^2+x^2y^3
б)-p^5q^8(p^3+3pq-q^4) = -p^8q^8-3p^6q^8+p^5q^12
в)-c^3d^4(c^2-d^3) = -1^5d^4+c^3d^7
г)r^7s^12()r^10+2rs-s^5) = r^17s^12+2r^8s^13-r^7s^17

26.3 a) 3x(x+y)-3x^2 = 3x^2+3xy-3x^2 = 3xy
б)7a(a-b)-7a^2 = 7a^2-7ab-7a^2 = -7ab
в)5c(c^2-d^2)-5c^3 = 5c^3-5cd^2-5c^3 = -5cd^2
г)10m(m^5+n^6) -10m^6 = 10m^6+10mn^6-10m^6 = 10mn^6
