The second example is a greater rate of reading.

In order to come to that conclusion, I didn't do any figuring, ciphering,
numerating, or calculating of any kind. I just sat there and looked at
the question. I noticed that the second example is <u>more pages</u> than
the first one, but done in <u>less time</u> than the first one. So I know that
it must be a greater rate of cranking out the pages.

The first rate is 18/36 = 0.5 While the second rate is 20/30 = 0.6666666 So the second rate is greater.

You can do this using synthetic division, which is the easiest way. If x - 2 = 0, then x = 2. That 2 will go outside the "box" and the leading coefficients of the terms in the polynomial will go inside the "box". 2 (1 -3 -10 24). Bring down the first number, the 1. Multiply that 1 by the 2 to get 2. Put that 2 up under the -3 and add to get -1. Multiply that -1 by the 2 to get -2. Put that =-2 up under the -10 and add to get -12. Multiply that -12 by the 2 to get -24. Put the -24 up under the 24 and add to get 0. That means that x - 2 is a factor of the polynomial. What's left, the bolded numbers, are the coefficients of a new polynomial that is one degree less than the polynomial you started with. In other words, when we divide your polynomial by x-2, you get $x^2-x-12$ .
