Answer 2

${\huge{\sf{\bold{\boxed{\color{Pink}{Answer}}}}}}$

Let us say, the two consecutive positive integers be x and x + 1.

Therefore, as per the given statement,

$\tt x^2 + (x + 1)^2 = 365$

$\tt ⇒ x^2 + x^2 + 1 + 2x = 365$

$\tt ⇒ 2x^2 + 2x – 364 = 0$

$\tt ⇒ x^2 + x – 182 = 0$

$\tt ⇒ x^2 + 14x – 13x – 182 = 0$

$\tt ⇒ x(x + 14) -13(x + 14) = 0$

$\tt ⇒ (x + 14)(x – 13) = 0$

Thus, either, x + 14 = 0 or x – 13 = 0, [/tex]

$\tt ⇒ x = – 14 or x = 13$

since, the integers are positive, so x can be 13, only.

So, x + 1 = 13 + 1 = 14

Therefore, the two consecutive positive integers will be 13 and 14
