Question 235999: The product of two consecutive positive odd integers is one less than three times their sum. Find the integers.

A ladder is resting against a wall. The top of the ladder touches the wall at a height of 12 feet. Find the length of the ladder if the length is 8 feet more than its distance from the wall.

Let represent a positive odd integer. Then the next consecutive positive odd integer must be .

The product:

The sum:

One less than that:



Which is to say:



Solve the quadratic (it factors). Exclude the negative root because the problem asked for positive odd integers. The positive root is one of the integers. Add 2 to get the other one.
==================================================

The ladder, the ground, and the wall, presuming that the wall and the ground form a right angle, form a right triangle with sides 12, and , and hypotenuse
