Question
Find the polynomial having roots at $ -50 $ , $ 0 $ , $ 10 $ and $ 5 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^4+35x^3-700x^2+2500x $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -50 $ | $ x+50 $ |
| $ 0 $ | $ x $ |
| $ 10 $ | $ x-10 $ |
| $ 5 $ | $ x-5 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+50 \right) \cdot x \cdot \left( x-10 \right) \cdot \left( x-5 \right) = x^4+35x^3-700x^2+2500x $$This page was created using
