Question
Find the polynomial having roots at $ -3 $ , $ -3 $ and $ -3 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3+9x^2+27x+27 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -3 $ | $ x+3 $ |
| $ -3 $ | $ x+3 $ |
| $ -3 $ | $ x+3 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+3 \right) \cdot \left( x+3 \right) \cdot \left( x+3 \right) = x^3+9x^2+27x+27 $$This page was created using
