Find roots of polynomial $$ p(x) = x^3-38x^2+37x $$

The roots of polynomial $ p(x) $ are:

$$ \begin{aligned}x_1 &= 0\\[1 em]x_2 &= 37\\[1 em]x_3 &= 1 \end{aligned} $$

Step 1:

Factor out $ \color{blue}{ x }$ from $ x^3-38x^2+37x $ and solve two separate equations:

$$ \begin{aligned} x^3-38x^2+37x & = 0\\[1 em] \color{blue}{ x }\cdot ( x^2-38x+37 ) & = 0 \\[1 em] \color{blue}{ x = 0} ~~ \text{or} ~~ x^2-38x+37 & = 0 \end{aligned} $$

One solution is $ \color{blue}{ x = 0 } $. Use second equation to find the remaining roots.

Step 2:

The solutions of $ x^2-38x+37 = 0 $ are: $ x = 1 ~ \text{and} ~ x = 37$.
