if the sum of two numbers is 18 and the sum of their squares is 180 , then the product of the numbers is
"according to the given conditions x + y = 18 and x ^ 2 + y ^ 2 = 180 now ( x + y ) ^ 2 = x ^ 2 + y ^ 2 + 2 xy so 18 ^ 2 = 180 + 2 xy so xy = 144 / 2 = 72 answer : a"
divide(subtract(power(18, const_2), 180), const_2)
