Answer:

General quadratic polynomial equation is

\begin{gathered}{x}^{2} - ( \alpha + \beta )x + \alpha \beta = 0 \\ \\ {x}^{2} - ( \sqrt{2} + 1)x + \frac{1}{ \sqrt{2} + 1 } = 0 \\ \\ {x}^{2} - ( \sqrt{2} + 1)x + \frac{1}{ \sqrt{2} + 1 } \times \frac{ \sqrt{2} - 1 }{ \sqrt{2} - 1} = 0 \\ \\\red{\boxed{\green{ {x}^{2} - ( \sqrt{2} + 1)x + ({ \sqrt{2} - 1 } ) = 0}}}\end{gathered}
