explanation:
To resolve the expression, we will use the FOIL method
FOIL means
[tex]\begin{gathered} F=\text{FIRST} \\ O=\text{OUTER} \\ I=\text{INNER} \\ L=\text{LAST} \end{gathered}[/tex]The application of this to solve the question will be
[tex]\begin{gathered} (9p+8)(p+1) \\ \text{First}=9p\times p=9p^2 \\ \text{Outer}=9p\times1=9p \\ \text{Inner}=8\times p=8p \\ \text{Last}=8\times1=8 \end{gathered}[/tex]Thus, the answer will be
[tex]\begin{gathered} =>9p^2+9p+8p+8 \\ \Rightarrow9p^2+17p+8^{} \end{gathered}[/tex]Thus, the answer will be
[tex]undefined[/tex]
