im \: guessing \: its \: 4x {}^{2}  - 3x + 1 \\ (correct \: me \: if \: im \: wrong)

(a - b) {}^{2}  = a {}^{2}   - 2ab +  {b}^{2}

4x {}^{2}  = a {}^{2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: b {}^{2}  = 1 \\ a = 2x \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \: b = 1

(2x - 1) {}^{2}  = 4x {}^{2}   -4x + 1

we \: need \: to \: add \: a \: - x \\ \: to \: the \: original \: equation

<h2>Note that this problem can be approached in many ways. For instance, we can add to the b² term instead of changing the middle term...</h2>

Y=6 when x=18, find y when x=-12

so 6/18 = y/-12
cross multiplication
(6)(-12) = (18)(y)
-72 = 18y
divide both sides by 18
-4 = y

Hope this helps

1) The population

Is the set of all the terms that the teacher taught this semester and which he wrote down on the note cards and put in the paper bag.

2) The sample is every set of five cards that is selected by each student.

3) I think the sample is representative because all ther terms have the same probability of being selected. 

Further, given that the cards are replaced every time all the students will face the same population when they are going to select a sample.
