The root of polynomial $ p(x) $ is:
$$ \begin{aligned}x &= -\frac{ 3 }{ 98 } \end{aligned} $$Step 1:
Combine like terms:
$$ \color{blue}{4x} \color{red}{-34x} \color{green}{-34x} \color{green}{-34x} -3 = \color{green}{-98x} -3 $$Step 2:
$$ \begin{aligned} -98x-3 & = 0 \\[1 em] -98 \cdot x & = 3 \\[1 em] x & = \frac{ 3 }{ -98 } \end{aligned} $$
