Question
Find the polynomial having roots at $ 1 $ , $ 82 $ and $ 1 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3-84x^2+165x-82 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 1 $ | $ x-1 $ |
| $ 82 $ | $ x-82 $ |
| $ 1 $ | $ x-1 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-1 \right) \cdot \left( x-82 \right) \cdot \left( x-1 \right) = x^3-84x^2+165x-82 $$This page was created using
