Answer :

Let's find the polynomial that results from subtracting [tex]\(9a^2 - 6a + 5\)[/tex] from [tex]\(10a^2 + 3a + 25\)[/tex].

Follow these steps:

1. Write down the polynomials:

[tex]\[ (10a^2 + 3a + 25) - (9a^2 - 6a + 5) \][/tex]

2. Distribute the negative sign to the second polynomial:

[tex]\[ 10a^2 + 3a + 25 - 9a^2 + 6a - 5 \][/tex]

3. Combine like terms:

- For the [tex]\(a^2\)[/tex] terms:
[tex]\[ 10a^2 - 9a^2 = 1a^2 \][/tex]

- For the [tex]\(a\)[/tex] terms:
[tex]\[ 3a + 6a = 9a \][/tex]

- For the constant terms:
[tex]\[ 25 - 5 = 20 \][/tex]

4. Combine the results:

So, the result from the subtraction is:

[tex]\[ 1a^2 + 9a + 20 \][/tex]

Therefore, when you subtract [tex]\(9a^2 - 6a + 5\)[/tex] from [tex]\(10a^2 + 3a + 25\)[/tex], the resulting polynomial is:

[tex]\[ 1a^2 + 9a + 20 \][/tex]
