Question 350632
Hi,
Let x represent the smaller number.  Then (x+4) will be the other.
.
Question states
{{{x^2 + (x+4)^2 = 80}}}
.
{{{x^2 + x^2+ 8x +16 = 80}}}
.
{{{2x^2 + 8x +16 = 80}}}
.
{{{2x^2 + 8x -64 = 0}}}
.
factor
(2x - 8)(x+8) = 0
(x+8) = 0  this solution will not result in a positive number
.
(2x-8) = 0
x = 4
Numbers are 4 and 8
.
check your answer
16 + 64 = 80
