Question
Find the polynomial having roots at $ -100 $ , $ -100 $ and $ -100 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3+300x^2+30000x+1000000 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -100 $ | $ x+100 $ |
| $ -100 $ | $ x+100 $ |
| $ -100 $ | $ x+100 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+100 \right) \cdot \left( x+100 \right) \cdot \left( x+100 \right) = x^3+300x^2+30000x+1000000 $$This page was created using
