please answer this i will mark as brilianist who gave the write answer​

Answer 1

Answer:

a^3-4a^2+5a-6-(a^2-2a+1)

a^3-4a^2+5a-6-a^2+2a-1

a^3-5a^2+7a-7

Answer 2

Answer:

a³-5a²+6a-7.

Step-by-step explanation:

Le the required number to be subtracted be x.

Then, a³-4a²+5a-6-x=a²-2a+1

=>a³-4a²+5a-6-(a²-2a+1)=x

=>a³-4a²+5a-6-a²+2a-1=x

=>x=a³-5a²+6a-7

Therefore, the required number is a³-5a²+6a-7.
