Find the polynomial having roots at $ 1 $ , $ -2 $ and $ 6 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3-5x^2-8x+12 $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 1 $ | $ x-1 $ |
| $ -2 $ | $ x+2 $ |
| $ 6 $ | $ x-6 $ |
Step 2: Multiply the factors together:
$$ P(x) = \left( x-1 \right) \cdot \left( x+2 \right) \cdot \left( x-6 \right) = x^3-5x^2-8x+12 $$This page was created using
