Question
Find the polynomial having roots at $ 0 $ , $ -7 $ and $ -3 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3+10x^2+21x $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 0 $ | $ x $ |
| $ -7 $ | $ x+7 $ |
| $ -3 $ | $ x+3 $ |
Step 2: Multiply the factors together:
$$ P(x) = x \cdot \left( x+7 \right) \cdot \left( x+3 \right) = x^3+10x^2+21x $$This page was created using
