Answer:
The answer is: ![3x^2-14x+7](https://tex.z-dn.net/?f=3x%5E2-14x%2B7)
which agrees with answer B) among your list of possible options.
Step-by-step explanation:
I think you forgot an "x" in the first trinomial, so, let's try that:
![(5x^2-5x+1)-(2x^2+9x-6)=\\= 5x^2-5x+1-2x^2-9x+6=\\=3x^2-14x+7](https://tex.z-dn.net/?f=%285x%5E2-5x%2B1%29-%282x%5E2%2B9x-6%29%3D%5C%5C%3D%205x%5E2-5x%2B1-2x%5E2-9x%2B6%3D%5C%5C%3D3x%5E2-14x%2B7)
Solution :
1. A chart monitoring the object counts with some specific characteristic during the time period and/or some of consistent amount area -- c. c - chart
2. A chart which monitors the subgroup variations within the range of subgroups -- a. R chart
3. The chart monitoring the variation of within subgroup to that of the standard deviations of the subgroups -- d. s chart
4. The chart which monitors the objects' proportion from the sample size of n which does or does not have any particular characteristics -- g. p chart
5. The chart monitoring the averages between the subgroup of the quantitative characteristic keys -- b. x-"bar" chart
