Question
Find the polynomial having roots at $ 3 $ , $ 3 $ , $ 3 $ , $ 0 $ and $ 0 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^5-9x^4+27x^3-27x^2 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 3 $ | $ x-3 $ |
| $ 3 $ | $ x-3 $ |
| $ 3 $ | $ x-3 $ |
| $ 0 $ | $ x $ |
| $ 0 $ | $ x $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-3 \right) \cdot \left( x-3 \right) \cdot \left( x-3 \right) \cdot x \cdot x = x^5-9x^4+27x^3-27x^2 $$This page was created using
