Two integers are 26 and 28

Step-by-step explanation:

  • Step 1: Let the two consecutive positive integers be x and x + 2. Product = 728

x(x + 2) = 728

x² + 2x - 728 = 0

x = -2 ±√4 - 4 × 1 × -728/2 (using quadratic formula)

  = -2 ±√4 + 2912/2

  = -2 ±√2916/2 = -2 ± 54/2

  = -56/2, 52/2

  = -28, 26 (negative value is neglected)

∴ x = 26

x + 2 = 28
