Find roots of polynomial $$ p(x) = x^2+5x+6+x+2 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -2\\[1 em]x_2 &= -4 \end{aligned} $$Explanation
Step 1:
Combine like terms:
$$ x^2+ \color{blue}{5x} + \color{red}{6} + \color{blue}{x} + \color{red}{2} = x^2+ \color{blue}{6x} + \color{red}{8} $$Step 2:
The solutions of $ x^2+6x+8 = 0 $ are: $ x = -4 ~ \text{and} ~ x = -2$.
