Heya ✋
Let see your answer !!!!!
21a^3 - 17a^2 - (89a^3 - 64a^2 + 6a + 16)
= 21a^3 - 17a^2 - 89a^3 + 64a^2 - 6a - 16
= 21a^3 - 89a^3 - 17a^2 + 64a^2 - 6a - 16
= - 68a^3 + 47a^2 - 6a - 16
Hence , 21a^3 - 17a^2 is - 68a^3 + 47a^2 - 6a - 16 less than 89a^3 - 64a^2 + 6a + 16.
Thanks :)))))

Required expression is
89a³ -64a²+6a+16-(21a² -17a²)
=89a³-64a²+6a+16 -21a³ + 17a²
On combining the like terms,
= 89a³-21a³– 64a²+17a² + 6a+16
= 68a³-47a² + 6a+16
So,
21a³ -17a². is. 68a³-47a² + 6a+16 less than 89a² -64a²+6a+16.
I think my answer is capable to clear your confusion
