Question
Find the polynomial having roots at $ 18 $ and $ 40 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^2-58x+720 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 18 $ | $ x-18 $ |
| $ 40 $ | $ x-40 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-18 \right) \cdot \left( x-40 \right) = x^2-58x+720 $$This page was created using
