$$\frac{\sqrt{26} - \sqrt{13} - \sqrt{2}+1}{\sqrt{13} -1 }= ? $$
My attempt:
$$\frac {\sqrt{2}. \sqrt{13} - \sqrt{13}-2 +1}{2} \tag 1$$ Which equals to $$\frac {\sqrt{2}-1}{\sqrt{13} +1} \tag 2 = ...$$
Waiting for your helps.

\begin{align}\frac{\sqrt 2 \cdot \sqrt{13}-\sqrt{13}-\sqrt2+1}{\sqrt{13}-1}&=\frac{\sqrt{13}(\sqrt 2 -1)-1 (\sqrt2-1)}{\sqrt{13}-1}\\&=\frac{(\sqrt{13}-1)(\sqrt 2-1)}{\sqrt{13}-1}\\&=\sqrt2-1 \end{align}
