Question
Find the polynomial having roots at $ -2 $ , $ 5 $ , $ 10 $ , $ 0 $ and $ 0 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^5-13x^4+20x^3+100x^2 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -2 $ | $ x+2 $ |
| $ 5 $ | $ x-5 $ |
| $ 10 $ | $ x-10 $ |
| $ 0 $ | $ x $ |
| $ 0 $ | $ x $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+2 \right) \cdot \left( x-5 \right) \cdot \left( x-10 \right) \cdot x \cdot x = x^5-13x^4+20x^3+100x^2 $$This page was created using
