Answer 2

Let's simplify the given expression:

(-12a² + 5a) + (a + 11a²) - (a² - 1)

First, let's combine like terms within each set of parentheses:

-12a² + 5a + a + 11a² - a² + 1

Next, let's group the terms with the same power of 'a' together:

(-12a² + 11a²) + (5a + a) - a² + 1

Simplifying further:

(-1a²) + (6a) - a² + 1

Combining like terms:

-1a² - a² + 6a + 1

Finally, we can combine the 'a²' terms:

-2a² + 6a + 1

So the simplified expression is -2a² + 6a + 1.
