the sum of the squares of three numbers is 100 , while the sum of their products taken two at a time is 48 . their sum is :
"x ^ + y ^ 2 + z ^ 2 = 100 xy + yz + zx = 48 as we know . . ( x + y + z ) ^ 2 = x ^ 2 + y ^ 2 + z ^ 2 + 2 ( xy + yz + zx ) so ( x + y + z ) ^ 2 = 100 + ( 2 * 48 ) ( x + y + z ) ^ 2 = 196 so x + y + z = 14 answer : e"
add(multiply(sqrt(divide(subtract(100, 48), const_2)), const_100), sqrt(subtract(100, divide(subtract(100, 48), const_2))))
