| ① | Multiply each term of $ \left( \color{blue}{16+x}\right) $ by each term in $ \left( 12+2x\right) $. $$ \left( \color{blue}{16+x}\right) \cdot \left( 12+2x\right) = 192+32x+12x+2x^2 $$ |
| ② | Combine like terms: $$ 192+ \color{blue}{32x} + \color{blue}{12x} +2x^2 = 2x^2+ \color{blue}{44x} +192 $$ |
