Question 66527: The length of Jims leader is always 2 feet shorter than the length of his fishing rod. If the product of the length of the leader and the length of the rod equals strength of his line in lbs and he uses 16 lbs line, What is the length of his leader?

length of fishing rod = r
length of the leader = r - 2
(length of fishing rod)(length of the leader) = strength of line in pounds
(r)(r - 2) = 16
r^2 - 2r = 16
(r - 1)^2 = 17
r - 1 = +-
r =
You can use other ways to solve the quadratic function.
