Q. A polynomial function f(x) with integer coefficients has a leading coefficient of 2 and a constant term of 1. According to the Rational Root Theorem, which of the following are possible roots of f(x)?Multi-select Choices:(A) 34(B) 21(C) 1(D) 101
Understand Rational Root Theorem: The Rational Root Theorem states that any rational root, expressed in its lowest terms qp, must have p as a factor of the constant term and q as a factor of the leading coefficient.
List Factors of Constant Term: List the factors of the constant term, which is 1: ±1.
List Factors of Leading Coefficient: List the factors of the leading coefficient, which is 2: ±1, ±2.
Form Possible Fractions: Form all possible fractionsp/q using the factors of the constant term for p and the factors of the leading coefficient for q: ±1/1, ±1/2.
Simplify Fractions: Simplify the fractions to get the possible rational roots: ±1,±21.
Check Given Options: Check the given options against the possible rational roots: (A) 34 is not a possible root because 3 is not a factor of the leading coefficient. (B) 21 is a possible root. (C) 1 is a possible root. (D) 101 is not a possible root because 10 is not a factor of the leading coefficient.
