**Reiny**, Thursday, February 2, 2012 at 8:29pmone number --- x

the other ---- 10-x

x^2 + (10-x)^2 = 52

x^2 + 100 - 20x + x^2 = 52

2x^2 - 20x + 48 = 0

x^2 - 10x + 24 = 0

(x-6)(x-4) = 0

x = 6 or x=4

if one is 6, the other is 4

if one is 4 the other is 6

(symmetrical answers)

the two numbers are 6 and 4

check: 6+4 = 10

36+16 = 52

all is good!
