Question
Find the polynomial having roots at $ \dfrac{ 3 }{ 2 } $ and $ \dfrac{ 5 }{ 2 } $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 4x^2-16x+15 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ \dfrac{ 3 }{ 2 } $ | $ 2x-3 $ |
| $ \dfrac{ 5 }{ 2 } $ | $ 2x-5 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( 2x-3 \right) \cdot \left( 2x-5 \right) = 4x^2-16x+15 $$This page was created using
