Step-by-Step Solution
Solution:
Step 1: Understand the input vector
The vectorppcontains coefficients of a polynomial in descending powers.Step 2: Understand the
Therootsfunctionrootsfunction calculates the values ofxwhere the polynomial equals zero.Final Answer:
The roots (zeros) of the polynomial represented byp-> Option BQuick Check:
roots(p) = polynomial zeros [OK]
Quick Trick: roots() finds where polynomial equals zero [OK]
Common Mistakes:
- Confusing roots() with derivative or integral functions
- Thinking roots() returns polynomial degree
- Assuming roots() returns coefficients
