Question
Find the polynomial having roots at −32 , −21 and 1 .
Answer
The polynomial generated from the given zeros is: P(x)=6x3+x2−5x−2
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
−32 | 3x+2 |
−21 | 2x+1 |
1 | x−1 |
Step 2: Multiply the factors together:
P(x)=(3x+2)⋅(2x+1)⋅(x−1)=6x3+x2−5x−2
