| ① | Multiply $ \color{blue}{3} $ by $ \left( -3x+5\right) $ $$ \color{blue}{3} \cdot \left( -3x+5\right) = -9x+15 $$ |
| ② | Remove the parentheses by changing the sign of each term within them. $$ - \left(-9x+15 \right) = 9x-15 $$ |
| ③ | Combine like terms: $$ 9x \color{blue}{-15} + \color{blue}{5} = 9x \color{blue}{-10} $$ |
