Find the polynomial having roots at $ -3 $ , $ 4 $ and $ -\dfrac{ 3 }{ 2 } $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 2x^3+x^2-27x-36 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -3 $ | $ x+3 $ |
| $ 4 $ | $ x-4 $ |
| $ -\dfrac{ 3 }{ 2 } $ | $ 2x+3 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+3 \right) \cdot \left( x-4 \right) \cdot \left( 2x+3 \right) = 2x^3+x^2-27x-36 $$This page was created using
