① | Multiply $ \color{blue}{3} $ by $ \left( x-2\right) $ $$ \color{blue}{3} \cdot \left( x-2\right) = 3x-6 $$Multiply $ \color{blue}{2} $ by $ \left( x+6\right) $ $$ \color{blue}{2} \cdot \left( x+6\right) = 2x+12 $$ |
② | Combine like terms: $$ \color{blue}{3x} \color{red}{-6} + \color{blue}{2x} + \color{red}{12} = \color{blue}{5x} + \color{red}{6} $$ |
