Answer 1

Answer : The polynomial in standard form is
`1a^2+9a+20`

Step-by-step explanation :

The polynomial in standard form means that the terms are ordered from highest exponent to lowest exponent.

Given: Subtract
`9a^2-6a+5` from
`10a^2+3a+25`

The expression will be :

`(10a^2+3a+25)-(9a^2-6a+5)`

Now open the bracket and change the sign.

`=10a^2+3a+25-9a^2+6a-5`

Now we are adding or subtracting the like terms, we get:

`=1a^2+9a+20`

Thus, the polynomial in standard form is
`1a^2+9a+20`
