The sum of two numbers is given and product is also given find the square of difference of two numbers.

• ans: (a-b)^2 = (a+b)^2 - 4ab

• let the two numbers be x and y.
  sum of two numbers=x+y
  product of numbers=xy
  so the square of difference of two numbers is given as,
  (x-y)^2=(x+y)^2-4xy

• ans - its very simple ...jst apply (a-b)^2 = a2 + b2 - 2ab
• 12 years agoHelpfull: Yes(2) No(1)
• too easy
  a^2-b^2=(a+b)^2-4ab

• let A be the one no.
  and B be the second no.
  (A-B)^2=(A+B)^2-(4AB)
