What is the sum of the leading coefficient and the constant term of the polynomial P(y) = y³ − 3y² + 2y − 1?
Think it through first, then pick an option.
- a 1
- b 0
- c − 1
- d − 3
Answer and explanation
Correct answer: b 0
The leading coefficient is 1 and the constant term is −1; the sum is 0.
Why the other options are wrong
- a 1: 1 is only the leading coefficient; the constant term −1 must be added.
- c − 1: −1 is only the constant term; the leading coefficient 1 must be added.
- d − 3: −3 is the coefficient of y², which is neither the leading coefficient nor the constant term.
