let one odd positive integer be (x+1) so another one becomes (x+3)
now it is given that
(x+1)^2 + (x+3)^2 = 290
x^2 + 1 + 2x + x^2 + 9 + 6x = 290
2x^2 + 8x + 10 = 290
2x^2 + 8x = 280
OR 2x^2 +8x - 280 = 0
on dividing the equation by 2 we get
x^2 + 4x - 140 = 0
On solving this equation we will get 2 values of x.
i.e. +10 and -12
Since positive is given so put the positive value of x and find the numbers
- 11
- 13
these are the numbers
