The difference between two numbers is 9 and the product of the two is 14. What is the square of their sum?

a) 120 b) 130 c) 137 d) 145

Read Solution (Total 1)

Take two numbers as x and y
The difference between two numbers = x-y = 9
The product of the two numbers = x*y = 14
The square of the two numbers sum = (x+y)^2 = (x-y)^2 + (4*x*y) = 9^2 + (4*14) = 81+56 = 137
Hence, option is 'c'
