| ① | Multiply each term of $ \left( \color{blue}{7x+10}\right) $ by each term in $ \left( x-6\right) $. $$ \left( \color{blue}{7x+10}\right) \cdot \left( x-6\right) = 7x^2-42x+10x-60 $$ |
| ② | Combine like terms: $$ 7x^2 \color{blue}{-42x} + \color{blue}{10x} -60 = 7x^2 \color{blue}{-32x} -60 $$ |
