2.11 Add and subtract like terms CN9 Combine any like terms in the expression. If there are no like terms, rewrite the expre \( 44 p+26 p q+2 p+4 p q \)

To combine like terms in the expression \( 44 p + 26 pq + 2 p + 4 pq \), first identify the terms that are similar. The like terms for \( p \) are \( 44 p \) and \( 2 p \), which add up to \( 46 p \). The like terms for \( pq \) are \( 26 pq \) and \( 4 pq \), which combine to \( 30 pq \). So the simplified expression is \( 46 p + 30 pq \). To double-check your work, you can take a step-by-step approach. First, write down the terms clearly: all \( p \) terms together and all \( pq \) terms together. Then carefully add them one type at a time—this helps avoid missing anything! It's a great habit to develop for more complex expressions later on.
