Correct answer only melissa is using synthetic division to divide. which answer is correct?

Without even lifting your pencil, you can eliminate a and d. The leading coefficient has nothing to do with what you are dividing by. The question is should you be using 1 or - 1 on the outside of the division sign?  

The one you have marked is absolutely correct. You could check it by long division if you know how to do that better than synthetic division.  Set it up like this.

x - 1 || 3x^3 - x^2- 9x + 7 || 3x^2 + 2x - 7

is what you get doing it the long hard way.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
