Let the two consecutive positive integers be x and x + 1
Then,
x2 +(x+1) 2 =365
⇒x2 +x2 + 2x + 1 = 365
⇒2 x2 +2x − 364 = 0
⇒x2 + x − 182 = 0
Using the quadratic formula, we get
x= 2 −1 ± 1 + 728
⇒2 − 1 ± 27
⇒x = 13 and x = −14
But x is given to be a positive integer.
∴x1 = −14
Hence, the two consecutive positive integers are 13 and 14.
