Find the polynomial having roots at $ 0 $ , $ 4 $ and $ 4 $ .
Answer
The polynomial generated from the given zeros is: $ P(x) = x^3-8x^2+16x $
Explanation
Step 1: Turn the zeros into factors:
| Zero | Factor |
| $ 0 $ | $ x $ |
| $ 4 $ | $ x-4 $ |
| $ 4 $ | $ x-4 $ |
Step 2: Multiply the factors together:
$$ P(x) = x \cdot \left( x-4 \right) \cdot \left( x-4 \right) = x^3-8x^2+16x $$This page was created using
