Step 1

Roots are the points where the graph intercepts with the x-axis $(y = 0)$ .

$y = 0$ at the roots

Step 2

The root at $x = - \frac{1}{3}$ was found by solving for $x$ when $x - (- \frac{1}{3}) = y$ and $y = 0$ .

The factor is $x + \frac{1}{3}$

Step 3

The root at $x = \sqrt{11}$ was found by solving for $x$ when $x - (\sqrt{11}) = y$ and $y = 0$ .

The factor is $x - \sqrt{11}$

Step 4

The root at $x = - 2 i$ was found by solving for $x$ when $x - (- 2 i) = y$ and $y = 0$ .
