Answer:
A) 
Step-by-step explanation:
Given expression:

To factor the given expression completely.
Solution:
In order to factor the expression, we will factor in pairs.

We will factor the G.C.F of the terms in the pairs.
G.C.F. of
and
can be given as:


Thus, G.C.F. = 
G.C.F. of
and
can be given as:


Thus, G.C.F. = 
The expression after factoring the G.C.F. pairs is given as:

Taking G.C.F. of the whole expression as
is a common term.

The expression is completely factored.
The roots of 54 are: 1 and 54, 2 and 27, 3 and 18, 6 and 9, then it restarts all over again.
The two numbers have to multiply up to 54, and add up to 3. 9 and 6 have a difference of 3, and the multiplied sum is negative, so this is your pair.
9 and -6 fit this criteria, since they add up to 3 and multiply to 64.
6 remainder 4 because if you do 8x6 you get 48 and if you subtract 48 from 52 you get remainder 4
M=y2-y1/x2-x1
6-5/8-0
1/8
The answer is A
Hope this helps!
