A/C to question
let two number are x and y
sum of two positive number
x+y= 14. ...(1)
Again,
x²-y²= 56 ...(2)
or,
(x+y)(x-y) = 56
By (1)
(14)(x-y) = 56
x-y= 56/14
x-y= 4 ....(3)
so, equation (1) + (3)
we get
2x= 18
x= 9
and ,by (1)
we get,
9+y= 14
y= 14-9
y= 5
Thus :--
value of
x²+y²
= 9²+5²
= 81+25
= 106
