Answer:

\huge{\boxed{\boxed{\sf{x^{2}-14x+41}}}}

Step-by-step explanation:

\huge{\boxed{\boxed{\underline{\sf{SOLUTION-}}}}}

 \alpha  = 7 + 2 \sqrt{2}  \\  \beta  = 7 - 2 \sqrt{2}  \\ according \: to \: the \: question \\( x -  \alpha )(x -  \beta )=0 \\  = )(x - (7 + 2 \sqrt{2} ))(x - (7 - 2 \sqrt{2} )) =0\\  = )(x - 7 - 2 \sqrt{2} )(x -  7  + 2 \sqrt{2} )=0 \\ \\we \: know \:  {x}^{2}  -  {y}^{2}   = (x + y)(x - y)=0 \\ \\so \: we \: conclude \: this \: in \: this \: answer \\  = )(x - 7)^{2}  - (2 \sqrt{2} )^{2} =0 \\  = ) {x}^{2}  +  {7}^{2}  - 14x - 4 \times 2 =0\\  = ) {x}^{2}  + 49 - 14x - 8 =0\\  = ) {x}^{2}  - 14x  + 41=0

\huge{\boxed{\boxed{\sf{x^{2}-14x+41}}}}
