Question
Find the polynomial having roots at 55 , 9 and 3 .
Answer
The polynomial generated from the given zeros is: P(x)=x3−67x2+687x−1485
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
55 | x−55 |
9 | x−9 |
3 | x−3 |
Step 2: Multiply the factors together:
P(x)=(x−55)⋅(x−9)⋅(x−3)=x3−67x2+687x−1485
