Question
Find the polynomial having roots at −2 , 2 , −3 , 3 , 4 and −4 .
Answer
The polynomial generated from the given zeros is: P(x)=x6−29x4+244x2−576
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
−2 | x+2 |
2 | x−2 |
−3 | x+3 |
3 | x−3 |
4 | x−4 |
−4 | x+4 |
Step 2: Multiply the factors together:
P(x)=(x+2)⋅(x−2)⋅(x+3)⋅(x−3)⋅(x−4)⋅(x+4)=x6−29x4+244x2−576
