Find 2 consecutive odd integers such that their product is 11 more than 2 times their sum
Answer provided by our tutors
The 2 consecutive odd integers can be written as:
2x - 1 and 2x + 1, where x is integer.
The product of the 2 consecutive odd integers is 11 more than 2 times their sum
(2x - 1)(2x + 1) = 11 + 2*(2x - 1 + 2x + 1)

x1 = 3
x2 = -1
For x = 3 we have:
2*3 - 1 = 5
2*3 + 1 = 7
For x = -1 we have:
2*(-1) - 1 = -3
2*(-1) + 1 = -1
We have found two solutions:
The two consecutive odd integers are 5 and 7.
The two consecutive odd integers are -3 and -1.
