<h2>Answer:</h2>
The answer is 16.
<h2>Step-by-step explanation:</h2>Since the 8x is positive, the equation must have y as a positive number.

An easy way to complete the square if you have the constants for x2 and
But not the non-variable number is to divide the x constant, and then square it.
Example:
The last number must be 16. Let's check it.
