Question
Find the polynomial having roots at $ 3 $ and $ -\dfrac{ 12 }{ 5 } $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 5x^2-3x-36 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 3 $ | $ x-3 $ |
| $ -\dfrac{ 12 }{ 5 } $ | $ 5x+12 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-3 \right) \cdot \left( 5x+12 \right) = 5x^2-3x-36 $$This page was created using
