Problem: if the sum of two numbers is 22 and the sum of their squares is 386 , then the product of the numbers is
Rationale: "sol . let the numbers be x and y . then , ( x + y ) = 22 and x 2 + y 2 = 386 . now , 2 xy = ( x + y ) 2 - ( x 2 + y 2 ) = ( 22 ) 2 - 386 = 484 - 386 = 98 xy = 49 . answer b"
annotated_formula: divide(subtract(power(22, const_2), 386), const_2)
