The expression (4a³ + 5a² - 2a) - (4a³ - 11a² + 3a) can be simplified as follows:
Start by combining the two like terms:
4a³ - 4a³ = 0
Next, combine the remaining terms:
0 + 5a² - 11a² + (-2a + 3a) = -6a² + a = -6a² + a
So, the simplified expression is:
0 + -6a² + a = -6a² + a
This is the final answer.
