Transcript text: $\left(3 h^{2}+7 h+5\right)-\left(3 h^{2}+h+5\right)$

Solution

Step 1: Expand the expression

The given expression is: \[ (3h^{2} + 7h + 5) - (3h^{2} + h + 5) \]

First, distribute the negative sign to the terms inside the second parentheses: \[ 3h^{2} + 7h + 5 - 3h^{2} - h - 5 \]

Step 2: Combine like terms

Combine the terms with the same degree of $ h $:

So, the expression simplifies to: \[ 6h \]

\[ \boxed{6h} \]
