| ① | Multiply the numerator and denominator by the conjugate of the denominator . $$\color{blue}{ \sqrt{14}} $$. |
| ② | Multiply in a numerator. $$ \color{blue}{ 17 \sqrt{12} } \cdot \sqrt{14} = 34 \sqrt{42} $$ Simplify denominator. $$ \color{blue}{ \sqrt{14} } \cdot \sqrt{14} = 14 $$ |
| ③ | Divide numerator and denominator by $ \color{blue}{ 2 } $. |
