The product of two consecutive odd integers is 10 more than the square of the smaller integer. Find the integers.
-----------
1st: 2x-1
2nd: 2x+1
-----
(2x-1)(2x+1) = (2x-1)^2+10
4x^2-1 = 4x^2 - 4x + 1 + 10
4x = 12
x = 3
1st = 2x-1 = 5
2nd = 2x+1 = 7

The product of two consecutive odd integers is 10 more than the square of the smaller integer. Find the integers.

Step 1. Let n be one odd number and n+2 be the next consecutive odd number

Step 2. Let n*(n+2) be the product of the two odd integers

Step 3. Let n%5E2 be the square of the smaller integer.

Step 4. n*(n+2)=n^2+10 since the product of two consecutive odd integers is 10 more than the square of the smaller integer. Solve yields the following steps:

n%2A%28n%2B2%29=n%5E2%2B10

n%5E2%2B2n=n%5E2%2B10

2n=10 divide by two to both sides

2n=10%2F2

n=5 and n%2B2=7

Check 5%2A7=5%5E2%2B10 which is a true statement

Step 5. The numbers are 5 and 7.

I hope the above steps were helpful.
