Question
Find the polynomial having roots at $ -3 $ , $ \dfrac{ 301 }{ 400 } $ and $ 5 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 400x^3-1101x^2-5398x+4515 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -3 $ | $ x+3 $ |
| $ \dfrac{ 301 }{ 400 } $ | $ 400x-301 $ |
| $ 5 $ | $ x-5 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+3 \right) \cdot \left( 400x-301 \right) \cdot \left( x-5 \right) = 400x^3-1101x^2-5398x+4515 $$This page was created using
