The given expression is:

[64a³ – 144a² + 108a – 27] – [64a³ + 144a² + 108a + 27]

To simplify this, we subtract the terms in the second bracket from the corresponding terms in the first bracket.

64a³ - 64a³ = 0
-144a² - 144a² = -288a²
108a - 108a = 0
-27 - 27 = -54

So, the simplified expression is:

0 - 288a² + 0 - 54 = -288a² - 54

Question

The given expression is:
