The sum of squares of two numbers ia 80 and the square of difference between two numbers is 36. Find the product of two numbers. Correct Answer 22

মনেকরি, সংখ্যাদ্বয় x ও y প্রশ্নমতে, x2 + y2 + 80.........(i)(x - y)2 = 36 .......(ii)(i)⇒ x2 + y2 + 80⇒(x - y)2 + 2xy = 80⇒  36  +  2xy  =  80  ⇒  2xy  =  44⇒  xy  =  22
