Using synthetic division, find (x4 − 2) ÷ (x + 1).

Fiesta28 [93]

Answer:

Step-by-step explanation:

We have given:

x^4-2/x+1

Put x+1 = 0

x= 0-1

x= -1

-1 | 1 0 0 0 -2

| -1 1 -1 1

_______________

1 -1 1 -1 -1

Thus it makes the expression:

x^3-x^2+x-1 - 1/x+1

You can further confirm this expression by solving the expression:

(x4 − 2) ÷ (x + 1).

x^4 - 1 -1/x+1

x^4-1/x+1 - 1/x+1

(x^2-1) (x^2+1)/x+1 - 1/x+1

(x-1)(x+1) (x^2+1)/x+1 - 1/x+1

x+1 n the numerator will be cancelled out by x+1 in the denominator.

(x-1) (x^2+1) - 1/x+1

Multiply (x^2+1) by x-1

x(x^2+1) -1(x^2+1) - 1/x+1

x^3+x-x^2-1 - 1/x+1

x^3-x^2+x-1 - 1/x+1 ....

Important need to know??????????????????

Mean: Add all of the numbers together, then divide by how many numbers there are. So, your mean is 40.6 (Rounded to the nearest tenth)

Median: The middle number (when they are in order). So, your median is 44.

Mode: The mode is whatever number appears the most; however, since there are no repeating numbers, there is no mode for this data set.

Range: Range is the difference between the highest and lowest values of the data set. So, your range is 55.

Let me know if you need any further explanation! :)

These are the values in Irwin’s data set.

grin007 [14]

The residual points include the difference between the value in Irwin's dataset and the predicted values

<h3>How to plot the residuals?</h3>

The residual is calculated using:

Residual = Actual points - Predicted points

The actual points are:

(1,43), (3, 36), (5,22), (6, 25), (8,14)

The predicted points are:

(1,44), (3, 35), (5,26), (6, 22), (8,13)

Using the residual formula above, we have the residuals to be:

(x,y) = (1,-1), (3, 1), (5,-4), (6, 3), (8,1)

See attachment for the residual plot
