Question
Find the polynomial having roots at −31 , −2 and −3 .
Answer
The polynomial generated from the given zeros is: P(x)=3x3+16x2+23x+6
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
−31 | 3x+1 |
−2 | x+2 |
−3 | x+3 |
Step 2: Multiply the factors together:
P(x)=(3x+1)⋅(x+2)⋅(x+3)=3x3+16x2+23x+6
