Unique method. Great!
@@ManishaTopno-v8u It is simple method only..When I solved x^2-22x+117=0 ,I got this idea.117=121-4=(11+2)(11-2)=13×913+9=22The roots are 13,9.
391=400-9=20^2-3^2=23×17527=529-2=576-49=24^2-7^2=31×17.Use a^2-b^2=(a+b)(a-b)
Wow yaar very easy it is

When I solved x^2-22x+117=0 ,I got this idea.
117=121-4=(11+2)(11-2)=13×9
13+9=22
The roots are 13,9.
391=400-9=20^2-3^2=23×17
527=529-2=576-49=24^2-7^2=31×17.
Use a^2-b^2=(a+b)(a-b)
