Answer 3

To subtract the polynomials (-9a^2 + 9a + 4) and (-7a^2 + 4), follow these steps:

1. Start by distributing the negative sign to each term inside the parentheses of the second polynomial:
(-7a^2 + 4) becomes -7a^2 + (-4).

2. Next, combine like terms by grouping the terms with the same exponent of 'a':
-9a^2 - 7a^2 = -16a^2
9a - 0 = 9a
4 - (-4) = 4 + 4 = 8

3. Now, write the simplified polynomial by combining the terms obtained in the previous step:
The result is: -16a^2 + 9a + 8.

Therefore, the correct answer to the subtraction of the polynomials is -16a^2 + 9a + 8, not -16a^2 + 9a as you stated.
