To simplify the expression $\frac{2}{7 - 3\sqrt{2}}$, we need to rationalize the denominator. Here are the steps:

1. Multiply the numerator and the denominator by the conjugate of the denominator: The conjugate of $7 - 3\sqrt{2}$ is $7 + 3\sqrt{2}$.

$\frac{2}{7 - 3\sqrt{2}} \cdot \frac{7 + 3\sqrt{2}}{7 + 3\sqrt{2}} = \frac{2(7 + 3\sqrt{2})}{(7 - 3\sqrt{2})(7 + 3\sqrt{2})}$

2. Simplify the denominator using the difference of squares:

$(7 - 3\sqrt{2})(7 + 3\sqrt{2}) = 7^2 - (3\sqrt{2})^2 = 49 - 18 = 31$

3. Combine the results:

$\frac{2(7 + 3\sqrt{2})}{31} = \frac{2 \cdot 7 + 2 \cdot 3\sqrt{2}}{31} = \frac{14 + 6\sqrt{2}}{31}$

So, the simplified form of $\frac{2}{7 - 3\sqrt{2}}$ is:

$\frac{14 + 6\sqrt{2}}{31}$
