Let the numbers be a and b
a-b=3
a^2+b^2=117
(a-b)^2=a^2+b^2-2ab
3^2=117-2ab
2ab=117-9
2ab=108
(a+b)^2=a^2+b^2+2ab
(a+b)^2=117+108
√(a+b)^2=√225
(a+b)=15
A-b=3
2a=18
A=9
a-b=3
a^2+b^2=117
(a-b)^2=a^2+b^2-2ab
3^2=117-2ab
2ab=117-9
2ab=108
(a+b)^2=a^2+b^2+2ab
(a+b)^2=117+108
√(a+b)^2=√225
(a+b)=15
A-b=3
2a=18
A=9
