Question
Find the polynomial having roots at $ -\dfrac{ 7 }{ 2 } $ and $ -\dfrac{ 11 }{ 2 } $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = 4x^2+36x+77 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -\dfrac{ 7 }{ 2 } $ | $ 2x+7 $ |
| $ -\dfrac{ 11 }{ 2 } $ | $ 2x+11 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( 2x+7 \right) \cdot \left( 2x+11 \right) = 4x^2+36x+77 $$This page was created using
