if the sum of two numbers is 42 and their product is 437 , then find the absolute difference between the numbers .
let the numbers be x and y . then , x + y = 42 and xy = 437 x - y = sqrt [ ( x + y ) 2 - 4 xy ] = sqrt [ ( 42 ) 2 - 4 x 437 ] = sqrt [ 1764 – 1748 ] = sqrt [ 16 ] = 4 . required difference = 4 . answer is b .
sqrt(subtract(power(42, const_2), multiply(const_4, 437)))
