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
click here to see the step by step solution of the equation
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.
