Answer:

We know ,

(a+b)2=a2 +b2 +2ab  

36=28+2ab  

8=2ab  

ab=4  

As ,  a+b=6  

a+4a=6  

a2+4=6a  

a2−6a+4=0  

a=−(−6)±36−16√2  

a=−(−6)±20√2  

a=6±25√2  

a=3±5√1  

a=3+5–√,3−5–√  

Therefore,

the two numbers are ,  3+5–√,3−5–√  

Hope this answer helps you … Have a great day ahead !!!
