Answer 1

а) p(a+b) = pa+pb
б) -y(k+c) = -yk-yc
в) a(k+c-3) = ak+ac-3a
г) -x(a-b+1) = -xa+xb-x
д) 5a^2(2-a) = 10a^2-5a^3
е) -7x^3(x^5+3x) = -7x^8-21x^4
ж) -8b^3(b-2b^2) = -8b^4+16b^5)
з) (y^15+y^20)12y^23 = 12y^38+12y^43
и) 2m^4(m^5-m^3-1) = 2m^9-2m^7-2m^4
к) 2x(3x^2+5xy-y^2) = 6x^3+10x^2y-2xy^2
л) -3c(c^3+c-4) = -3c^4-3c^2+12c
м) b^5(b^6-5b^3+b-3) = b^11-5b^8+b^6-3b^5
н) (8a^2-4a+16)0.25a = 2a^3-a^2+4a
о) -9p(2p^4+p^2-2p+1) = -18p^5-9p^3+18p^2-9p
