Find the polynomial having roots at $ 3 $ , $ \dfrac{ 1 }{ 2 } $ and $ 0 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 2x^3-7x^2+3x $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 3 $ | $ x-3 $ |
| $ \dfrac{ 1 }{ 2 } $ | $ 2x-1 $ |
| $ 0 $ | $ x $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-3 \right) \cdot \left( 2x-1 \right) \cdot x = 2x^3-7x^2+3x $$This page was created using
