One polynomial, denoted as P(x), is defined as P(x) = x^3 - 7x^2 + x + 25. Which of the following options correctly represents this polynomial?

A) P(x) = x^3 - 7x^2 + x + 25
B) P(x) = x^3 - 7x^2 + x - 25
C) P(x) = x^3 + 7x^2 + x + 25
D) P(x) = x^3 - 7x^2 - x + 25

Answer :

Final answer:

The correct representation of the polynomial [tex]P(x) = x^3 - 7x^2 + x + 25[/tex] is Option A, as it exactly matches the predefined expression of P(x).

Explanation:

The student asked which of the following options correctly represents the polynomial [tex]P(x) = x^3 - 7x^2 + x + 25[/tex]. The correct representation of this polynomial is Option A) [tex]P(x) = x^3 - 7x^2 + x + 25[/tex]. This is because this option directly matches the predefined expression for P(x). In a polynomial, each term is represented as a product of a coefficient and the variable x raised to a power, starting from the highest power moving down to the constant term (if present). Understanding the structure of polynomials is crucial for various operations like differentiation, integration, and solving polynomial equations.
