Question
Find the polynomial having roots at $ 777 $ , $ 7 $ and $ 71 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3-855x^2+61103x-386169 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 777 $ | $ x-777 $ |
| $ 7 $ | $ x-7 $ |
| $ 71 $ | $ x-71 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-777 \right) \cdot \left( x-7 \right) \cdot \left( x-71 \right) = x^3-855x^2+61103x-386169 $$This page was created using
