| ① | Multiply each term of $ \left( \color{blue}{7h+10}\right) $ by each term in $ \left( -3+5h\right) $. $$ \left( \color{blue}{7h+10}\right) \cdot \left( -3+5h\right) = -21h+35h^2-30+50h $$ |
| ② | Combine like terms: $$ \color{blue}{-21h} +35h^2-30+ \color{blue}{50h} = 35h^2+ \color{blue}{29h} -30 $$ |
