Final answer:

The student is requesting the partial fraction decomposition of a rational expression with repeated linear factors, which requires factoring the denominator and setting up a decomposition that aligns with the form of the original denominator's factors.

Step-by-step explanation:

The question is asking for the partial fraction decomposition of the given rational expression with repeated linear factors in the denominator. To find the partial fraction decomposition of
\((-x^2-x+16)/(x^3+8x^2+16x)\),, recognizing that it represents a polynomial with repeated linear factors. The complete factorization of
\(x^3+8x^2+16x\) is \(x(x+4)^2\).ition will take the form:


\[(-x^2-x+16)/(x(x+4)^2) = (A)/(x) + (B)/(x+4) + (C)/((x+4)^2)\]

Next, you would multiply both sides by the denominator to remove the fraction and equate the coefficients of corresponding powers of
\(x\) sides to find the values of
\(A\), \(B\), and \(C\) manipulation and possibly solving a system of equations.
