The solution of the equation is 
and 
Explanation:
Given that the equation is 
We need to determine the solution of the equation by completing the square.
Thus, we have,
Adding both sides of the equation by 16, we get,
Let us solve by completing the square.
To bring the equation in the form of 
, let us add 
to both of the equations.
Thus, we have,
Simplifying, we get,
Taking square root on both sides of the equation, we get,
Thus, the two solutions of the quadratic equation are
and 
Simplifying the two values, we get,
and
Thus, the roots of the equation are and

The distance from Dan's house to Samuel's house is 4 km
The distance from Dan to Samuel house, Dan to Cindy house and Samuel to Cindy house forms a right angled triangle.
Distance from Dan to Samuel house = x, Distance from Dan to Cindy house = 3 km and Distance from Cindy to Samuel house = 5 km
Pythagoras theorem shows the relationship between the lengths of a right angled triangle.
Using Pythagoras theorem:
5² = x² + 3²
25 = x² + 9
x² = 16
x = 4 km
Hence the distance from Dans house to Samuel's house is 4 km
