We can simplify this expression by combining like terms.
To combine like terms, we are looking for terms that share the same variable and exponent.
First, we can see that the terms
and
share the same variable (h) and the same exponent (2).

This simplifies to
.
Next, we can see that
and
share the same variable (h) and the same exponent (1) so we can add these.

This simplifies to
.
Lastly, we can see that we just have 7, no more terms with the same variable (none). So this is 7.
Adding up all the terms in standard form (
), we get
.
Hope this helped!
