It decreases the number of data by one.
Answer: 
Step-by-step explanation:
You can do long division, which is very very hard to show with typing on a keyboard. You essentially want to divide the leading coefficient for each term. Ill try my best to explain it.
Do
. Write 2x^2 down. Now multiply (x - 3) by it. Then subtract it from the trinomial.

Now do
. Write that down next to your 2x^2. Multiply 3x by (x - 3) to get:

Your final step is to do
. Write this -2 next to your other two parts
Multiply -2 by (x - 3) to get:

Our remainder is 0 so that means (x - 3) goes into that trinomial exactly:
times
Answer:
8 (3/4)
Step-by-step explanation:
convert everything into improper frantions
-3 1/2 = -7/2
-12 1/4 = -49/4
common denominators
-7/2 = -14/4
solve
-(14/4)-(-49/9)
two negative cancel out to make a positive
-(14/4)+(49/9)
35/4
35 divided by 4 = 8.75 = 8 3/4
