Question
Find the polynomial having roots at $ -7 $ and $ -5 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^2+12x+35 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -7 $ | $ x+7 $ |
| $ -5 $ | $ x+5 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+7 \right) \cdot \left( x+5 \right) = x^2+12x+35 $$This page was created using
