x=numero 1 
10-x= numero 2 


x^2 + (10-x)^2 = 58 
x^2 + 100 -20X + x^2 = 58 
2x^2 - 20X + 42 = 0 ....simplificando 
x^2 - 10X + 21 = 0...factorizamos 

(x-3)(x-7)=0 ...resolvemos las dos partes 
x-3=0 -----> x=3 
x-7=0------>x=7 

los dos numeros son 3 y 7 

3^2 + 7^2 = 9+49= 58....Espero te sirva 



para el comentario de arriba 36 + 16=52..
