Question
Find the polynomial having roots at 5 , 2 , 3 and 0 .
Answer
The polynomial generated from the given zeros is: P(x)=x4−10x3+31x2−30x
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
5 | x−5 |
2 | x−2 |
3 | x−3 |
0 | x |
Step 2: Multiply the factors together:
P(x)=(x−5)⋅(x−2)⋅(x−3)⋅x=x4−10x3+31x2−30x
