Find the polynomial having roots at $ 1 $ , $ -8 $ and $ -6 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3+13x^2+34x-48 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 1 $ | $ x-1 $ |
| $ -8 $ | $ x+8 $ |
| $ -6 $ | $ x+6 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-1 \right) \cdot \left( x+8 \right) \cdot \left( x+6 \right) = x^3+13x^2+34x-48 $$This page was created using
