Question
Find the polynomial having roots at $ 170 $ , $ 18 $ and $ 70 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3-258x^2+16220x-214200 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 170 $ | $ x-170 $ |
| $ 18 $ | $ x-18 $ |
| $ 70 $ | $ x-70 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-170 \right) \cdot \left( x-18 \right) \cdot \left( x-70 \right) = x^3-258x^2+16220x-214200 $$This page was created using
