Question

5 - 9 - 5p How can I simplify the expression by combining like terms

Answer 1

Given the initial expression

$5-9-5p$

Notice that p^0=1; thus,

$5-9-5p=5p^0-9p^0-5p$

Combining terms that are multiplied by p^0,

$\begin{gathered} \Rightarrow5-9-5p=(5-9)p^0-5p \\ =(-4)p^0-5p \\ =-4-5p \end{gathered}$

The answer is -4-5p
