Answer:
In mathematics, we call multiplying a number by itself “squaring” the number. We call the result of squaring a whole number a square or a perfect square. A perfect square is any number that can be written as a whole number raised to the power of 2. For example, 9 is a perfect square.
Step-by-step explanation:
Both terms have a

in common, so we can pull it out. The factored form will be

times whatever is left after pulling it out.
In the first term, we will have just 8 left since everything else in the term is factored out.
The second term has a

left. Notice that both of these terms no longer have a negative sign since the negative was factored out.
The answer is
Answer:
The slope of FG is -1
Step-by-step explanation:
Given
Square EFGH
EF: 
Required
Determine the slope of FG
First, we calculate the slope of EF

Make y the subject


The general equation has the form: 
Where

Compare
to 

<em>From the name of the square EFGH, we can conclude that EF and FG are perpendicular</em>
<em />
The relationship between perpendicular lines is:

Where
-- Slope of EF
and
m2 = slope of FG
Substitute 1 for m1 in 


<em>Hence, the slope of FG is -1</em>
