- The sum of squares of two numbers is 80 and the square of their difference is 36.
Question 1:
The sum of squares of two numbers is 80 and the square of their difference is 36.The product of the two numbers is:
A. 44
B. 58
C. 22
Feedback Numbers be a and b.
=> a2 + b2 = 80 and (a - b) 2 = 36
=> (a - b) 2 = 36
=> a2 + b2 – 2ab = 36
=> 2ab = (a2 + b2) – 36 = 80 – 36 = 44
=> ab = 22.
=> a2 + b2 = 80 and (a - b) 2 = 36
=> (a - b) 2 = 36
=> a2 + b2 – 2ab = 36
=> 2ab = (a2 + b2) – 36 = 80 – 36 = 44
=> ab = 22.
D. 4 1/4
