Find the polynomial having roots at $ 9 $ , $ 5 $ , $ 7 $ , $ -8 $ and $ 0 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^5-13x^4-25x^3+829x^2-2520x $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 9 $ | $ x-9 $ |
| $ 5 $ | $ x-5 $ |
| $ 7 $ | $ x-7 $ |
| $ -8 $ | $ x+8 $ |
| $ 0 $ | $ x $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-9 \right) \cdot \left( x-5 \right) \cdot \left( x-7 \right) \cdot \left( x+8 \right) \cdot x = x^5-13x^4-25x^3+829x^2-2520x $$This page was created using
