My math test is tommorrow and I know there's a question like this on the test (from my math book).
The bed of a pond can be modeled by 25y = 2x^2 - 20x + 1, where x and y are measured in meters and the x-axis matches the water level of the pond. What is the width of the pond?
(HINT: This was in "Solving Quadratic Equations by Completing the Square" section) :wink:
