Find the Equation Given the Roots -216

$- 216$

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 $x = - 216$ was found by solving for $x$ when $x - (- 216) = y$ and $y = 0$ .

The factor is $x + 216$

Step 3

Combine all the factors into a single equation.

$y = x + 216$

Step 4

Remove parentheses.

$y = x + 216$
