Solution:-
_____________
let the first number be x and second be y respectively
So ,ATQ
x+y =>9 (eq1)
x^2+y^2=41 (eq2)
___________________
from eq1
y=>x-9
putting in eq2
x^2+(x-9)^2=41
x^2+x^2-18x+81=>41
2x^2-18x+40=>0
2(x^2-9x+20)=>0
x^2-9x+20=>0
x^2-5x-4x+20=>0
x(x-5)+4(x-5)=>0
(x-5)(x+4)=>0
x=>5,-4
