Question
Find the polynomial having roots at $ -9 $ and $ \dfrac{ 1 }{ 2 } $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 2x^2+17x-9 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -9 $ | $ x+9 $ |
| $ \dfrac{ 1 }{ 2 } $ | $ 2x-1 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+9 \right) \cdot \left( 2x-1 \right) = 2x^2+17x-9 $$This page was created using
