Question

sum of two number is 15 and the difference of their squares is 15 the difference of the number is

Answer 1

it's all about possibility check the paira of numbers from 1 to 10 to get 15 and do the square of numbers and compare the result suppose ex.


9+6
(9×9)=81
(6×6)=36
81-36=45 so their difference is not 15 so wrong pair

now let's take
8+7
(8×8)=64
(7×7)=49
64-49=15 so their difference is 15 so 8 and 7 are the numbers
