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 Pythagorean Theorem is a^2 + b^2 = c^2
It’s usually used on triangles when two sides are given but one isn’t. C represents the hypotenuse while A and B are interchangeable. So solving for the hypotenuse would look like √a^2+ b^2= c but solving for a or be would look like √c^2-b^2 = a and √c^2-a^2= b.
So number wise √5^2+12^2 = 13
