Question
Find the polynomial having roots at 11 , 17 , 0 and 7 .
Answer
The polynomial generated from the given zeros is: P(x)=x4−35x3+383x2−1309x
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
11 | x−11 |
17 | x−17 |
0 | x |
7 | x−7 |
Step 2: Multiply the factors together:
P(x)=(x−11)⋅(x−17)⋅x⋅(x−7)=x4−35x3+383x2−1309x
