Question
For each factor of the form \((px + q)^m\), the partial fraction decomposition must include the following sum of \(m\) fractions:

\[
\frac{A_1}{px + q} + \frac{A_2}{(px + q)^2} + \frac{A_3}{(px + q)^3} + \cdots + \frac{A_m}{(px + q)^m}
\]

For each factor of the form \((ax^2 + bx + c)^n\), the partial fraction decomposition must include the following sum of \(m\) fractions:

\[
\frac{B_1x + C_1}{ax^2 + bx + c} + \frac{B_2x + C_2}{(ax^2 + bx + c)^2} + \frac{B_3x + C_3}{(ax^2 + bx + c)^3} + \cdots + \frac{B_nx + C_n}{(ax^2 + bx + c)^n}
\]

**Example:** 

\[
\int \frac{x^3}{x^2 + 4x + 3} \, dx
\]
