To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
2. The first thing you must do to factor the expression is to group the terms, as following:
3. Now, choose the greatest common factor of each group:
4. Now, you need to factor the expression by factoring out the
The answer is:
The quadratic model is f(x) = -5x^2 + 200.
f(x) = 50 meters
x = time in seconds
50 = -5x^2 + 200
5x^2 = 150 // Here, divide both side by 5
x^2 = 30
x =
