Answer:
Choice B
Step-by-step explanation:
We can perform a least squares regression model in Ms. Excel to determine the equation of the line of best fit for the data given;
The first step is to enter the data into any two adjacent columns of an excel workbook. Next, click on the Data ribbon followed by the Data Analysis tool pack. We then proceed to select regression from the pop-up window. The final step is to select the y range and the x range of values from our data.
Once we click ok, Excel returns our least squares regression model as shown in the attachment below.
The coefficient of X variable 1 is our slope.

Answer:
x2 • (x2 - 32772)
Step-by-step explanation:
step 1: ((x4) - 22x2) - 32768x2
step 2: Pull out like factors :
x4 - 32772x2 = x2 • (x2 - 32772)
Factoring: x2 - 32772
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 32772 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares.
