Write out the form of the partial fraction decomposition of the function (See Example). Do not determine the numerical values of

maw [93]

Answer:

a. $\frac{A}{x}+\frac{B}{x^2}+\frac{C}{x^3}+\frac{Dx+E}{x^2+5}$

b. $\frac{A}{x+3}+\frac{B}{x-3}+\frac{C}{(x-3)^2}+\frac{D}{(x+3)^2}$

Explanation:

a.We are given that

$\frac{x^4+7}{x^5+5x^3}$

$\frac{x^4+7}{x^5+5x^3}=\frac{x^4+7}{x^3(x^2+5)}$

Using partial fraction decomposition of the given function

$\frac{x^4+7}{x^3(x^2+5)}=\frac{A}{x}+\frac{B}{x^2}+\frac{C}{x^3}+\frac{Dx+E}{x^2+5}$

Using the formula

$\frac{1}{x^3(x^2+a)}=\frac{A}{x}+\frac{B}{x^2}+\frac{C}{x^3}+\frac{Dx+E}{x^2+a}$

b. $\frac{2}{(x^2-9)^2}$

$\frac{2}{(x^2-3^2)^2}=\frac{2}{(x+3)^2(x-3)^2}$

Using property $a^2-b^2=(a+b)(a-b)$

$\frac{2}{(x+3)^2(x-3)^2}=\frac{A}{x+3}+\frac{B}{x-3}+\frac{C}{(x-3)^2}+\frac{D}{(x+3)^2}$

Using the property

$\frac{1}{x^2}=\frac{A}{x}+\frac{B}{x^2}$
