Step-by-step explanation:
Hello!
To find the greatest common factor, you must find all the factors of both numbers and see which similar one is the greatest.
27: (1,27) (3,9)
36: (1,36) (2,18) (3,12) (4,9) (6,6)
As you can see the, the greatest common factor is 9.
I hope this helps!
Answer:
A
Step-by-step explanation:
Answer:
To do this, you need to multiply out the expressions. This is a bit tedious, but remember like FOIL for binomials, for these trinomials you must multiply each term. If you need a step-by-step, I'd be happy to provide it. Let me know.
Once you have simplified the expression, you get
-x-9/2x-4
But, the problem stipulates that a must equal 1. We can equivalently factor out the negative sign and put it on the denominator with no change to write
x+9/-(2x-4) = x+9/-2x+4
So, seeing where each coefficient corresponds between the two expressions, you get a = 1, b = 9, c = –2, and d = 4.
