Find the polynomial having roots at $ -2 $ , $ 0 $ , $ 7 $ and $ -8 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^4+3x^3-54x^2-112x $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ -2 $ | $ x+2 $ |
| $ 0 $ | $ x $ |
| $ 7 $ | $ x-7 $ |
| $ -8 $ | $ x+8 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x+2 \right) \cdot x \cdot \left( x-7 \right) \cdot \left( x+8 \right) = x^4+3x^3-54x^2-112x $$This page was created using
