If the sum of two numbers is 42 and their product is 437, then what is the difference between these numbers?

• 4 is the difference between those numbers.
  
  Numbers are 19 and 23
  
  19 +23 =42
  19 *23 =437
  
  23 -19 =4(Difference)

• Adding 23 + 19 = 42
  Product 23 * 19 = 437
  Difference = 23 - 19 = 4
  Answer: 4

• x+y= 42
  x=42-y
  
  xy= 437
  (42-y)*y= 437 = 23*19
  
  so x-y = 4

• ans=4
  given x+y=42 and xy=437
  now according to maths
  (x+y)^2-4xy=(42)^2-4*437
  x^2+y^2+2xy-4xy=16
  x^2+y^2-2xy=16
  (x-y)^2=16
  x-y=4
  therefore difference is 4
