Question
Find the polynomial having roots at 8 , −3 and −2 .
Answer
The polynomial generated from the given zeros is: P(x)=x3−3x2−34x−48
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
8 | x−8 |
−3 | x+3 |
−2 | x+2 |
Step 2: Multiply the factors together:
P(x)=(x−8)⋅(x+3)⋅(x+2)=x3−3x2−34x−48
