Question

What is the standard form of a polynomial `(10y^2 + 22y + 18) - (7y^2 + 19y + 7)`?

Answer 1

`3y^2 +3y+11`

Explanation:

First, we have to subtract `7y^2` from `10y^2`, which is `3y^2`.

We also subtract `19y` from `22y`, which is `3y`, and subtract `7` from `18`. Finally, put together the same terms which are

`3y^2+3y+11`

This is the standard form.
