Question
Find the polynomial having roots at $ -2 $ , $ -8 $ , $ -7 $ and $ 6 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^4+11x^3-16x^2-404x-672 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -2 $ | $ x+2 $ |
| $ -8 $ | $ x+8 $ |
| $ -7 $ | $ x+7 $ |
| $ 6 $ | $ x-6 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+2 \right) \cdot \left( x+8 \right) \cdot \left( x+7 \right) \cdot \left( x-6 \right) = x^4+11x^3-16x^2-404x-672 $$This page was created using
