The polynomial generated from the given zeros is: $ P(x) = x^3-3x^2-18x $
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 0 $ | $ x $ |
| $ 6 $ | $ x-6 $ |
| $ -3 $ | $ x+3 $ |
Step 2: Multiply the factors together:
$$ P(x) = x \cdot \left( x-6 \right) \cdot \left( x+3 \right) = x^3-3x^2-18x $$
