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

Apr 27, 2017

$3 {y}^{2} + 3 y + 11$

#### Explanation:

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

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

$3 {y}^{2} + 3 y + 11$

This is the standard form.
