Answer» Answer: 13 and 14 Explanation: Let the two consecutive Numbers be x and x+1. x² + (x+1)² = 365 x² + x² +1² + 2*x*1 = 365 (because (A+B)² = A² + B²+ 2AB) or 2x² + 1 + 2x = 365 2x² + 2x = 365 - 1 2x² + 2x = 364 2(x² + x) = 364 or x² + x = 364/2 or x² + x = 182 or x² + x - 182 =0 Now Solve the Quadratic Equation , x² + 14x - 13x - 182 = 0 Note : - 13 *14 = 182 , this is because I write 14x - 13x instead of x , so as to solve the quadratic equation . x (x+14) - 13 (x +14 ) = 0 ( x- 13 )(x+14)=0 Therefore , Either x - 13 = 0 or x+14 =0 SINCE the Consecutive Integers are positive , Therefore , x-13 = 0 ⇒ x =13 hence One of the Positive Integers = 13 , therefore other positive INTEGER = x+1 = 13+1 = 14 So the two consecutive positive Integers are 13 and 14 .
