Question
Find the polynomial having roots at −514 , −517 , −519 and −521 .
Answer
The polynomial generated from the given zeros is: P(x)=625x4+8875x3+46925x2+109445x+94962
Explanation
Step 1: Turn the zeros into factors:
Zero | Factor |
−514 | 5x+14 |
−517 | 5x+17 |
−519 | 5x+19 |
−521 | 5x+21 |
Step 2: Multiply the factors together:
P(x)=(5x+14)⋅(5x+17)⋅(5x+19)⋅(5x+21)=625x4+8875x3+46925x2+109445x+94962
