It would be half of the coefficient of x squared added to both sides:
So half of 8 ( the coefficient of 8x) is 4;
The number 4 squared is 16, so you would add that to both sides.
You do this so that you can easily factor the left side: x^2 + 8x + 16 = 4 + 16
(x + 4)(x+4) = 20
Exact numbers are numbers are exact (and therefore have an unlimited number of significant figures)
<h3>What are exact numbers?</h3>
Exact numbers can be defined as numbers known with complete certainty.
These numbers have zero uncertainty and have infinite values.
Some examples of exact numbers are:
- counted numbers of objects or certain unit conversions such as 3 feet in 1 yard, exactly 12 eggs in a dozen
We can see that exact numbers have infinite values and thus have unlimited number of significant figures.
Thus, exact numbers are numbers are exact (and therefore have an unlimited number of significant figures)
