Problema Solution

The product of two consecutive odd integers is 29 less than 8 times their sum. Find the two integers.

Answer provided by our tutors

The two consecutive odd integers can be written as:


2x-1, 2x+1, where x is integer


the product of two consecutive odd integers is 29 less than 8 times their sum


(2x-1)(2x+1) = 8((2x-1) + (2x+1)) - 29


by solving we find


x1 = 1


x2 = 7

2*1 - 1 = 1


2*1 + 1 = 3


For x1 = 1 the numbers are 1 and 3.


2*7 - 1 = 13


2*7 + 1 = 15


For x1 = 7 the numbers are 13 and 15


There are two solutions for the problem, the frist solution is: numbers are 1 and 3; the second solution is the numbers are 13 and 15.
