x > 5 + x

x ² + x ² + 2 5 + 1 0 x = 7 3

2 x ² + 1 0 x = 7 3 - 2 5

x ² + x = 4 8 / 20

x ² = 48 / 40

x = sqrt 4 8 / 40

x = 0.1732

 \huge\blue{\underline{\underline{\bf Answer}}}

Let x and x +5 be the natural number..

Sum of the squares is 73

   \implies {x}^{2}   + {(x + 5)}^{2}  = 73 \\  \\  \implies  {x}^{2}  +  {x}^{2}  + 25 + 10x = 73 \\  \\  \implies 2 {x}^{2}  + 10x + 25 - 73 = 0 \\  \\  \implies 2 {x}^{2}  + 10x -  48 = 0 \\  \\ \implies  {x}^{2}  + 5x - 24 = 0 \\  \\  \implies x =  \frac{ - 5 +  \: or  \:   - \sqrt{ {5}^{2}  - 4(1)( - 24)}  }{2(1)}  \\  \\  \implies x =  \frac{ - 5 +  \: or \:  -  \sqrt{25 + 96} }{2}  \\  \\  \implies x =  \frac{ - 5 +  \: or \:  -   \sqrt{121} }{2}  \\  \\ \implies x =  \frac{ - 5 +  \: or \:  - 11}{2}  \\  \\  \implies \huge \boxed{ \: x = 3 \:  \:  \:  \: or \:  \:  \: x =  - 8}
