The root of polynomial $ p(x) $ is:
$$ \begin{aligned}x &= \frac{ 5 }{ 11 } \end{aligned} $$Step 1:
Combine like terms:
$$ \color{blue}{2x} + \color{blue}{9x} -5 = \color{blue}{11x} -5 $$Step 2:
$$ \begin{aligned} 11x-5 & = 0 \\[1 em] 11 \cdot x & = 5 \\[1 em] x & = \frac{ 5 }{ 11 } \end{aligned} $$
