Question
Find the polynomial having roots at 4 , 10 and 1 .
Answer
The polynomial generated from the given zeros is: P(x)=x3−15x2+54x−40
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
4 | x−4 |
10 | x−10 |
1 | x−1 |
Step 2: Multiply the factors together:
P(x)=(x−4)⋅(x−10)⋅(x−1)=x3−15x2+54x−40
