I'd use synthetic div. here, with 2 as my divisor:

________________
2 / 1 -11 18
2 -18
----------------------------
1 -9 0

Note that the coefficients of the missing factor are given here and are 1 and -9. Thus, (x-9) is the missing factor.

Answer:

Step-by-step explanation:

Subtracting a positive number moves you to the left on the number line. Subtracting a negative number moves you in the opposite direction, to the right.

Here, we start at -2 1/2 = -5/2, and we move 1 3/4 = 7/4 to the right from there. Each mark on this number line is 1/4 unit, so we move 7 marks. The results is ...

-2 1/2 -(-1 3/4) = -5/2 +7/4

= -10/4 +7/4 = -3/4
