To simplify the expression \(\frac{\sqrt{5} + 2}{\sqrt{3} - \sqrt{2}}\), we need to rationalize the denominator by multiplying both the numerator and denominator by the conjugate of the denominator. The conjugate of \(\sqrt{3} - \sqrt{2}\) is \(\sqrt{3} + \sqrt{2}\).

Let's proceed with the steps:

\[
\frac{\sqrt{5} + 2}{\sqrt{3} - \sqrt{2}} \times \frac{\sqrt{3} + \sqrt{2}}{\sqrt{3} + \sqrt{2}} = \frac{(\sqrt{5} + 2)(\sqrt{3} + \sqrt{2})}{(\sqrt{3} - \sqrt{2})(\sqrt{3} + \sqrt{2})}
\]

### Step 1: Simplify the denominator
The denominator is a difference of squares:
\[
(\sqrt{3} - \sqrt{2})(\sqrt{3} + \sqrt{2}) = (\sqrt{3})^2 - (\sqrt{2})^2 = 3 - 2 = 1
\]

### Step 2: Expand the numerator
Now, expand the numerator:
\[
(\sqrt{5} + 2)(\sqrt{3} + \sqrt{2}) = \sqrt{5} \cdot \sqrt{3} + \sqrt{5} \cdot \sqrt{2} + 2 \cdot \sqrt{3} + 2 \cdot \sqrt{2}
\]

This simplifies to:
\[
\sqrt{15} + \sqrt{10} + 2\sqrt{3} + 2\sqrt{2}
\]

### Final Expression:
Since the denominator is 1, the simplified expression is:
\[
\sqrt{15} + \sqrt{10} + 2\sqrt{3} + 2\sqrt{2}
\]

This is the final simplified form of the expression.
