Find the polynomial having roots at $ -1 $ , $ 6 $ , $ 0 $ and $ -8 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^4+3x^3-46x^2-48x $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -1 $ | $ x+1 $ |
| $ 6 $ | $ x-6 $ |
| $ 0 $ | $ x $ |
| $ -8 $ | $ x+8 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+1 \right) \cdot \left( x-6 \right) \cdot x \cdot \left( x+8 \right) = x^4+3x^3-46x^2-48x $$This page was created using
