Answer:
2k^3 -3k^2 -2k
Step-by-step explanation:
(2k^3-7k^2+3k)-(-4k^2+5k)
Distribute the minus sign
(2k^3-7k^2+3k)+4k^2-5k
Combine like terms
2k^3 -3k^2 -2k
Answer:
I hope i helped you! :)
Step-by-step explanation:
(2k^3-7k^2+3k)-(-4k^2+5k)=
(k×(2k^2-7k+3))+4k^2-5k=
(k×(2k^2-k-6k+3))+4k^2-5k=
(k×(k×(2k-1)-3(2k-1)))+4k^2-5k=
(k×(2k-1)×(k-3))+4k^2-5k=
k×(2k-1)×(k-3)+4k^2-5k=
k×((2k-1)×(k-3)+4k-5)=
k×(2k^2-6k-k+3+4k-5)=
k×(2k^2-3k-2)=
k×(2k^2+k-4k-2)=
k×(k×(2k+1)-2(2k+1))=
k×(2k+1)×(k-2)
