Find roots of polynomial $$ p(x) = 3x+4x+3 $$

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

$$ \begin{aligned}x &= -\frac{ 3 }{ 7 } \end{aligned} $$

Step 1:

Combine like terms:

$$ \color{blue}{3x} + \color{blue}{4x} +3 = \color{blue}{7x} +3 $$

Step 2:

$$ \begin{aligned} 7x+3 & = 0 \\[1 em] 7 \cdot x & = -3 \\[1 em] x & = - \frac{ 3 }{ 7 } \end{aligned} $$
