The product of two consecutive odd integers is 1 less than four times their sum.
Find the two integers.

We recall from Elementary Algebra that that we write two consecutive odd integers as:

Let: n = 1st number
n + 2 = 2nd number

Step 1 - Write the equation

Step 2 - Solve the equation

n2 + 2n = 4[2n + 2] - 1
n2 + 2n = 8n + 8 - 1
n2 + 2n = 8n + 7
n2 - 6n - 7= 0
(n - 7)(n + 1) = 0

We see to the right that we get
TWO sets of answers:

7 and 9
- 1 and 1
