Question
Find the polynomial having roots at $ \dfrac{ 15 }{ 2 } $ and $ 8 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 2x^2-31x+120 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ \dfrac{ 15 }{ 2 } $ | $ 2x-15 $ |
| $ 8 $ | $ x-8 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( 2x-15 \right) \cdot \left( x-8 \right) = 2x^2-31x+120 $$This page was created using
