| ① | Multiply each term of $ \left( \color{blue}{4x+2}\right) $ by each term in $ \left( 9x-3\right) $. $$ \left( \color{blue}{4x+2}\right) \cdot \left( 9x-3\right) = 36x^2-12x+18x-6 $$ |
| ② | Combine like terms: $$ 36x^2 \color{blue}{-12x} + \color{blue}{18x} -6 = 36x^2+ \color{blue}{6x} -6 $$ |
