Find roots of polynomial $$ p(x) = x+x-5 $$

The root of polynomial $ p(x) $ is:

$$ \begin{aligned}x &= \frac{ 5 }{ 2 } \end{aligned} $$

Step 1:

Combine like terms:

$$ \color{blue}{x} + \color{blue}{x} -5 = \color{blue}{2x} -5 $$

Step 2:

$$ \begin{aligned} 2x-5 & = 0 \\[1 em] 2 \cdot x & = 5 \\[1 em] x & = \frac{ 5 }{ 2 } \end{aligned} $$
