Write out the form of the partial fraction decomposition of the function (as in this example). do not determine the numerical values of the coefficients. (a) x4 − 2x3 + x2 + 3x − 2 x2 − 2x + 1

The form of the partial fraction decomposition of the function (x⁴ − 2x³ + x² + 3x − 2) ÷ x² − 2x + 1 without determining the numerical values of the coefficient is; x² + a/(x - 1) + b/(x - 1)²

The polynomial division of the function;

(x⁴ - 2x³ + x² + 3x -2)/(x² - 2x + 1). is as shown in the attached image.

Therefore, the result of the division is;

x² + (3x - 2)/(x² - 2x + 1)

However, because the function (x² - 2x + 1) can be expressed as a square in the form;

(x - 1)², so that we have;

x² + (3x - 2)/(x - 1)²

The general rule for partial fractions with repeated roots as in this case allows that the express be written as;

x² + a/(x - 1) + b/(x - 1)²

The degree of the numerator exceeds the degree of the denominator, so first you have to divide:

Now, , so the remainder term can be expanded to get

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
