Step-by-step explanation:
To complete the square, we first have to get our equation into form.
First we add 16x to both sides:
And now we subtract 62 from both sides.
We now have to add to both sides of the equation. b is 16, so this value becomes
.
We can now write the left side of the equation as a perfect square. We know that x+8 will be the solution because and
.
We can now take the square root of both sides.
We can now isolate x on one side by subtracting 8 from both sides.
So our solutions are

This seems like a right triangle problem.
So assuming 14 feet is the hypotenuse and 4 feet is a leg of the right triangle, we can use the pythagorean theorem () to solve for the height of the house, in which we shall name it x.
So, the equation is .
Solve for x:
16+x^{2}= 196
x^{2}= 196-16
x^{2}= 180
x = 6√5 feet
