(4a3b-10b3)+(-32b+10b3)
5a2-[a2+(5a2-2a)-2(a2-3a)]
(4a2b-3ab)+(5a2+2ab)
(5a2+5a-1)-4(3-8a+2a2
(4a3b-10b3)+(-32b+10b3)
5a2-[a2+(5a2-2a)-2(a2-3a)]
(4a2b-3ab)+(5a2+2ab)
(5a2+5a-1)-4(3-8a+2a2
4a3b-10b3)+(-32b+10b3) =4a³b-10b³-32ab+10b³=4b(a³-8)=4b(a-2)(a²+2a+4)=4b(a-2)(a+1)²
5a²-[a²+(5a²-2a)-2(a²-3a)]=5a²-(a²+5a²-2a-2a²+8a)=a²-6a=a(a-6)
(4a²b-3ab)+(5a²+2ab)=4a²b-3ab+5a²+2ab=4a²b+5a²-ab=a(4ab+5a-b)
(5a²+5a-1)-4(3-8a+2a²)=-3a²+37a-13
