Question
Find the polynomial having roots at $ -\dfrac{ 3 }{ 2 } $ , $ 3 $ and $ 6 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 2x^3-15x^2+9x+54 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -\dfrac{ 3 }{ 2 } $ | $ 2x+3 $ |
| $ 3 $ | $ x-3 $ |
| $ 6 $ | $ x-6 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( 2x+3 \right) \cdot \left( x-3 \right) \cdot \left( x-6 \right) = 2x^3-15x^2+9x+54 $$This page was created using
