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

(C) divide by 1

Step-by-step explanation:

when dividing by x - 1, set the expression equal to zero to find the zero.  That is actually what you are dividing by:

x - 1 = 0   ⇒   x = 1

so the number outside of the synthetic division symbol is 1.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
