Question
Find the polynomial having roots at $ 3 $ and $ \dfrac{ 53 }{ 20 } $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 20x^2-113x+159 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 3 $ | $ x-3 $ |
| $ \dfrac{ 53 }{ 20 } $ | $ 20x-53 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-3 \right) \cdot \left( 20x-53 \right) = 20x^2-113x+159 $$This page was created using
